An interview with science writer Melissa L. Sevigny about Brave the Wild River: The Untold Story of Two Women Who Mapped the Botany of the Grand Canyon

In late June 1938, three small boats pushed off from the banks of Green River, Utah, with plans to run the raging Colorado River through the Grand Canyon, all the way to Lake Mead. In addition to Grape Nuts, a bottle of Four Roses whiskey, and the latest USGS survey maps tied up with a “lucky string,” the boats carried something rather unusual on board: women.
At the time that Elzada Clover and her assistant, Lois Jotter, set out to become the first botanists to catalog the Grand Canyon, rumors still swirled that prehistoric creatures might lurk in its labyrinthine side canyons. Only 12 non-native expeditions had made the trip down the Colorado River since John Wesley Powell’s inaugural 1869 trip, and almost all of those rafters were men (the only woman to have attempted the journey vanished without a trace, along with her husband).
Though Clover and Jotter had serious work ahead of them, the contemporary coverage focused almost exclusively on the fact that the pair were women. Clover and Jotter weren’t much better respected by the men accompanying them; in addition to their significant scientific duties, they served as cooks for the crew on the entire 43-day journey. Even in spite of the distractions, though, Clover and Jotter’s catalog of over 400 species, including four previously unknown cactus species, remains the botanical ur-text of the region: “There was simply no other comprehensive plant list [of the Grand Canyon] published prior to the closure of Glen Canyon Dam,” explains science writer Melissa L. Sevigny’s Brave the Wild River: The Untold Story of Two Women Who Mapped the Botany of the Grand Canyon, an excellent new book about the river expedition. “Anyone who wanted to understand how the vegetation had changed — because of dams, exotic species, or any of the other human and natural influences at work on ecosystems in the past half-century — had to refer to Clover and Jotter’s work.”
Sevigny aimed to do Clover and Jotter justice by restoring them to their rightful place in science — and remembered history. But her book is also a rollicking, keep-you-up-at-night adventure story, told in utterly enveloping and immediate prose. Happily, Sevigny is earning her accolades; the book has received a rare triple-crown of early starred reviews from Publishers Weekly, Kirkus Reviews, and Booklist.
Brave the Wild River is out on May 23. Ahead of its publication, I had the chance to speak with Sevigny about Clover and Jotter, her writing process, and the continued uphill battle of women in the sciences today. Our conversation has been edited and condensed for clarity.
It was the fact that they were female scientists that drew me in. I always wanted to be a scientist; I wanted to be a geologist when I was a kid. I stayed on that path for quite a while and then I became a writer. I feel myself drawn to those stories because I suspect they might have changed things for me if I had known more stories about women in science when I was on that path.
I was surprised that I had never heard of these two women before, Elzada Clover and Lois Jotter. I’ve lived in Arizona all my life. I thought I knew a lot about its history, and yet somehow their names had never come up. Something about that really compelled me and the more I looked, the more I realized I couldn’t find what I was looking for, which was the story of the botanical work that they did. If I wanted to know that story, I was going to have to write it myself.
I was lucky enough right from the start to have the diaries of both of these women. A diary is such an immersive document, you really do feel like you’re in their heads. They’re writing things down that maybe they wouldn’t say out loud to anyone. And so I got to know them first through their diaries, which were wonderfully descriptive, and through letters, which are another really intimate form of communication. They had friends and family that they were very close with and that they would write these letters to on the trip. Whenever they could stop and post a letter, they would do that.
But I also had to do some other things to get into their heads and one of them was raft the Grand Canyon myself. I was incredibly nervous. I’d never done a whitewater rafting trip before. But I knew I was going to need to do that.
I went with a botany crew; we were tasked with weeding out an invasive species of grass. I wanted to do that so I could get a sense of what it was like to actually have to work as a botanist on the river. It was a small group: We had three boats and six people, just like they did. Of course, a lot of things have changed since 1938 about river rafting, but it did feel like a very immersive experience. I remember at one point, turning around to watch the boat behind me come through a rapid and I thought, ‘Oh, there’s Lorin Bell.’ That is a character from 1938 in my book; it was not, in fact, Lorin Bell. Time, it feels different down at the bottom of the Grand Canyon. And sometimes I did forget that it wasn’t 1938.
I’m grateful to them for having the foresight to keep the materials because while they were alive, people often told them — or gave them the impression — that what they did wasn’t that important. And if they had listened to those people, they wouldn’t have kept these materials. The fact that they saved their diaries, they saved their letters, they saved the newspaper clippings, and they donated them to these archives shows a lot of foresight and a lot of courage. I couldn’t have written this book if they hadn’t felt that way.
I did keep my own diary. I made sure I wrote in it every night. I also had a waterproof river map with me and I made notes on it before the trip of things I wanted to make sure I looked at. Because there would be a moment in the diaries where they would say, like, “We looked up and we saw the Desert View watchtower.” That would be the whole description. And so I knew, okay, stop and look up here so that you can describe what they were seeing.
When I got home, I typed up little bits of description out of my diary and I printed them out and I cut them up with scissors and then I actually would tape them into my draft and work at integrating them in.
That’s a direct quote from something that Lois Jotter said. I found out pretty quickly that both these women wanted to be remembered as botanists and they struggled because people wanted to talk about them as if they were the first women to succeed at rafting the Grand Canyon. Elzada Clover actually pushed back against that for a very specific reason: She would refer to herself as the first non-native woman to raft the Grand Canyon. She knew that the region had a long Indigenous history — Navajo and Hopi both have stories of running this river long before a white person came along and did it. Elzada knew that and so that was one reason she pushed back against that label.
But the second reason was that she did want to be remembered as a scientist, as a botanist, and I don’t think that really happened for her during her lifetime. But it’s difficult to center a story on science when the fact that they were women shaped so much of their experience. When I first dove into writing this book, I wanted to stay on the science and I really thought the sexism that they experienced would be a smaller thread — I thought it would be there, but I didn’t want it to center it. But as I was writing, it was impossible to ignore all of the obstacles they faced because they were women, so I hope I managed to strike the right balance and do justice to their story. It was a frustration for them when they were alive and it was a difficulty for me when I was writing, like “How can we tell this as a science story when they’re constantly being told that they shouldn’t be scientists?”
I think that’s absolutely right. And I’m glad you said you were shocked by that because I was fairly shocked too, and then I was embarrassed for being shocked. I expected going into it — this is embarrassing to admit — I really expected the sexism would almost be kind of funny, you know, it would be like, “Look at how those people acted in the 1930s!” And it is funny, but it’s a much darker humor than I expected because women are still facing all of these things today.
Maybe not to the same degree — it might be a little more hidden or subtle now — but all of the same things that [Clover and Jotter] experienced: struggle getting a job, struggle getting a promotion, struggle to be taken seriously, to have a seat at the table. Smaller things too, like people fixating on their physical appearance, telling them to smile. All of those things still happen to women today. I wasn’t expecting to write as much about that going into this book as I did, but I knew I had to because it was a very real part of their story and an extremely relevant part of their story.
It’s become only more relevant as time goes on. Clover and Jotter were the only people to make a formal plant list published in a Western scientific journal before Glen Canyon Dam went up. Today, there’s been a shift in thinking about the Colorado River. In their era, it was a given that people were going to build dams and they were going to harness this river. But today, a lot of people want to figure out how we can undo some of that damage, how we can protect the rivers, cultural values, and environmental values. And in that discussion, it’s hard to know how to do that if you don’t know what the river used to look like.
Clover and Jotter’s plant lists are just one part of that story. There’s also Indigenous wisdom about the plants along the river. There are other pre-dam records, but together it creates a picture of how this place used to look. Not saying that we can make it look like that again, but it gives us a way to pin our baselines in place so as we move forward, we can understand what kind of processes we need to restore this river. How do we want to protect it?
Yeah, so many things. Gosh. I was lucky to be able to track down some of their relatives and some of their former students and had really wonderful interviews with them. But there’s always questions, like, did you get it quite right?
There’s a key moment in the book where [Clover and Jotter] lose part of their plant collection and all I have are these little scraps and I don’t know exactly how that happened. Like, what were you planning? Who did you give that collection to, who was entrusted with it, and then what happened? I’d love to fill in those kinds of details.
I’d also like to ask them how they feel about how their botanical work has been used today. So many things changed from the 1930s to the present day and they lived through those changes, but because I don’t have as detailed records later in their life, I don’t know how they felt about what happened to the Colorado River, how they felt about how their work was used or ignored or misused over that time. I would just love to sit and talk with them about that. That’s one of many, many questions I would have.
This was a story about two ordinary women. I mean, I think they were remarkable, I wrote a whole book about them. But sometimes when we tell stories about science, we focus on the lone genius in the laboratory discovering a new element or breaking the laws of physics. Most science actually gets done in a much more incremental fashion. It’s about ordinary people who are passionate about some part of the natural world and they go out and they chase that curiosity and they move our knowledge forward. Just a little step. That’s what [Clover and Jotter] did and I think that’s how science works.
I started this conversation by saying that I wanted to be a scientist, right? I hope that young people or people of any age who are interested in science will see that it’s not something done by geniuses locked away in laboratories. Anybody can be a scientist.

Ford reveals a promising tidbit about its upcoming electric pickup.
When the Ford Fathom debuts in 2027, much of the attention will focus on its size and its price. As it should: The all-electric mid-size truck is promised to start under $30,000, and the success or failure of that car at that price will tell us a lot about the future of Ford, as well as mainstream America’s true appetite for EVs.
While we wait for our first real look at the truck and the full list of its specifications, Ford just revealed a promising tidbit. The automaker has been working in the background to make it simpler and cheaper for Fathom drivers to use bidirectional charging: the ability for power to flow both ways so that EV drivers can use the energy stored in the vehicle battery to power secondary loads, to back up a home power supply during a blackout, or even to feed back onto the power grid.
Specifically, Ford announced on Tuesday that the Fathom will be the first EV from a U.S. automaker with a starting price below $30,000 that does not need a separate wall-mounted inverter — the piece needed to transform the DC power stored in the car’s battery to the AC power used in the house. Instead, engineers built one into the truck’s “e-box” module that houses much of its electronics. That on-board unit is good enough to supply more than 10 kW of AC power to a home, Ford says.
Bidirectional charging isn’t new to American EVs or to Ford. The F-150 Lightning EV got this feature when it debuted five years ago. The trouble is that this game-changing technology doesn’t come cheap: The Lightning — now discontinued, soon to be revived as an extended-range EV — was an expensive ride starting above $50,000. The electrical hardware needed to connect the truck to one’s home power supply added thousands of dollars on top of the truck’s price.
The same was true for other EV makers. Two years ago, when I interviewed EV pickup drivers after Hurricane Helene hit North Carolina, I found F-150 Lightning and Tesla Cybertruck owners alike who hadn’t forked over more money for the extra tech needed to hook directly into the home. They got themselves through the blackout the Macgyver way, plugging the refrigerator and other critical appliances right into the power outlets in the back of the truck.
Ford’s Fathom, though, comes closer to giving the best of bidirectional charging to the masses. In addition to installing an on-board inverter, Ford says it will make the Ford Home Power Station and Home Backup Panel — the hardware that drivers will need to connect to the house — cost at least 60% less than the brand’s first-generation tech. The Detroit giant also says it’s working with a consortium of utilities, including American Electric Power, BC Hydro, Consumers Energy, Exelon, and Pacific Gas and Electric Co., to iron out how Fathom owners across the country will connect to their homes and the grid.
As Ford notes in its release: “There are more than 3,000 utilities across the U.S. and Canada with largely unique interconnection processes. Interconnection processes were primarily written for rooftop solar and stationary battery storage, which are fixed assets. Bidirectional EVs bring new considerations since they are vehicles first, not stationary equipment.”
Indeed, cooperation between car companies and utilities is suddenly a pressing matter as more EVs hit the roads, and the grid. Rivian and other electric car makers are trying to make their vehicles play nice with the power grid as a way for their customers to save money and reduce grid strain by having EVs charge when demand is low and electricity is cheap. And at some point, electric cars will become a major cog in virtual power plants — the ability of the power grid to pull energy from sources like EVs, backup batteries, and homeowner solar in times of need.
That day is finally approaching. Although bidirectional charging is a striking bonus feature for EVs, something so much more interesting and sophisticated than what a fossil fuel car can accomplish, the tech has flown fairly under the radar in the U.S. One could blame not only the lagging pace of EV adoption here, but also the fact that Tesla, far and away the market leader, has been slow to get on board. Just this month, it finally said that Model Y and Model 3 vehicles, the two best-selling electric cars in America, would get bidirectional capability.
The Ford Fathom, then, may do more than revitalize the lagging fortunes of Ford, which lost billions upon billions in its first forays into electrification and started up a skunkworks team to design the new truck in a totally different way. Their creation might also show Americans the EV’s enormous role in the home, and the grid, of tomorrow.
Current conditions: Tropical Storm Olana is headed for Hawaii with yet more flooding and powerful winds as the state continues to recover from previous storms • Tropical Cyclone Arnab is strengthening into a “severe” storm as it approaches the northern coast of India’s Andhra Pradesh state near the port city of Visakhapatnam • In-fa has become a typhoon, en route by the end of this week to the Northern Mariana Islands, the U.S. territory that took the brunt of this month’s Super Typhoon Champi.
Call it Anthropic’s magnum Opus 5.5. The Claude maker filed its public paperwork Monday ahead of its planned stock market debut. Aside from the basic details of how the company makes money and what risks its technology may pose to humanity itself, Anthropic mentions the word “energy” at least 14 times in the section of the document outlining the risks to its business. “Climate” and “climate change” are mentioned just four times. The overarching concern, per my colleague Matthew Zeitlin’s rundown of the S-1 filing, is that the company “might not get enough power for data centers running its large language models,” and that “the pace of the energy infrastructure build-out “is generally behind the need.
Brazil’s national oil company, meanwhile, had a brutal day of trading on the stock market following left-wing Brazilian President Luiz Inácio Lula da Silva’s surprise surge to reelection in Sunday’s runoff. Shares of Petrobras plunged 14% on the New York Stock Exchange by the time trading ended Monday evening. While conservative candidate Flávio Bolsonaro had promised more privatization and fewer environmental regulations, Lula has ramped up drilling, particularly offshore, as he seeks to capitalize on South America’s oil boom.

EQT Corporation bills itself as “America’s only large-scale, vertically integrated natural gas producer.” Soon it will also be the largest gas company in the nation. On Monday, the company announced plans to acquire Range Resources Corporation in a deal to create a North American gas giant worth more than $50 billion. The all-stock transaction would also establish the biggest gas producer in the U.S. by output. Combined, EQT and Range pump out 9 billion cubic feet of natural gas equivalent per day. The next largest shale gas producer in the U.S. is Expand Energy, at 7.5 billion cubic feet per day. The merged company would also command a network of pipelines and other midstream infrastructure that tops 3,700 miles. “This transaction brings together two of the highest-quality, longest-duration asset bases in North America and creates a company uniquely positioned for the next era of natural gas,” EQT CEO Toby Z. Rice said in a statement. “We believe this combination creates a must-own energy company capable of generating durable, through-cycle free cash flow while compounding value for shareholders for decades to come.”
The deal is a sign “U.S. gas consolidation is accelerating,” Salih Yilmaz, a senior oil analyst at the consultancy Bloomberg Intelligence, wrote in a post on X. “The bigger theme is consolidation: scale, concentration, and infrastructure control are becoming increasingly important in US gas, especially as LNG exports and power demand grow.”
U.S. orders for wind turbines vaulted to 2.8 gigawatts in the second quarter of this year — the highest since the end of 2023 — as developers scrambled to meet the deadlines to qualify for expiring tax credits, according to a new market analysis by the consultancy Wood Mackenzie. New Mexico saw the biggest surge as the SunZia megaproject, the largest wind farm ever built in the U.S., came online, raising the state to the top of the list of capacity additions. Despite the Trump administration’s efforts to kill or slow walk permits for wind projects, the industry is on track to add 39 gigawatts of new onshore wind farms by 2030. More than half the projects set to come online over the next two years are already under construction, meaning there’s little risk of disruption. Offshore wind, by contrast, tops out at 5 gigawatts, all of which is on course to be delivered in the next two years. “Policy is the variable with the greatest impact on wind installations,” Wood Mackenzie analyst Tyler Gifford said in a statement. “With tax credit expirations on the horizon, developers are prioritizing projects that can be operational by 2030, so the five-year onshore wind installation outlook remains stable.”
On the other side of the Atlantic, exports of wind turbines are booming. While Europe is still debating how to deal with the sudden rise of China’s wind companies, as I told you last week, the European Union's exports of wind turbines spiked by nearly 11% to $3.4 billion last year, Renewables Now reported.

The climate movement, as virtually anyone involved will tell you, is broken. Even those who are part of it want to stop talking about “climate change,” according to the results of this year’s Heatmap Insiders Survey. Clean Air Task Force, one of the more pragmatic groups in the policy arena fighting for clean energy, is out with a new memo detailing the strategy it plans to use through the end of the decade. Dubbed CATF Forward, the plan is “designed to drive the global adoption of climate solutions, orienting around three clear impact priorities and rooted in the attributes that have made” the group “uniquely effective” since its launch 30 years ago. “The world’s increasingly complex climate and energy challenges require sober thinking and sharper focus,” Armond Cohen, CATF’s founder and executive director, said in a statement. “How do we protect climate in a world turned upside down?”
His answer:
All of that seems fairly straightforward. But the document is defined as much by what it omits as what it includes. Amid a growing debate over whether climate activists should keep targeting fossil fuel infrastructure, which my colleague Robinson Meyer aired out nicely on a recent episode of our podcast Shift Key, CATF isn’t pushing for boycotts of fossil fuels or, you know, committing crimes in the name of saving the planet.
India’s solar factories have boomed in recent years as the world’s most populous country turns to photovoltaics to meet surging domestic electricity demand and supply overseas buyers looking for alternatives to China. But the subcontinent has struggled to take on China’s dominance of the solar supply chain’s upstream elements. On Monday, Noida-based Jakson Solar announced plans to invest over $525 million into manufacturing solar cells, ingots, and wafers. The company plans to commission a 3-gigawatt cell factory by the end of next year, managing director Ivan Saha told Reuters on the sideline of a conference. The company then plans to stand up a 3-gigawatt ingot and wafer plant by the third quarter of 2028. That will all feed into Jakson’s existing 1.2-gigawatt module-making factory.
Indonesia and Malaysia have launched more than 100 cloud-seeding missions this year in an attempt to engineer rain to quench parched lands as El Niño worsens droughts. The worst wildfire season in decades has shrouded the region in devastating toxic smog. But the high cost of the effort, including using dry ice to break up warm air that traps smog on the ground, “have so far brought little in the way of lasting results,” Bloomberg reported. “Sometimes, there’s a lot of political pressure to do things that may not be really well-founded scientifically,” Steven Siems, a professor at Monash University in Melbourne and the co-chair of an expert team on weather modification at the World Meteorological Organization, told the newswire.
It’s amazing what you can do with a repurposed car engine.
Venture capitalists love a system that fits inside a shipping container. But that kind of modularity has been hard to pull off in the low-carbon fuels industry, where producers have generally remained yoked to the prevailing wisdom of economies of scale as the key to profitability. That’s led to enormous, capital-intensive facilities packed with complex, custom-built machinery churning out fuels and chemicals like hydrogen, methane, and ammonia.
But Massachusetts-based startup Emvolon thinks it can upend this model with its compact, prefabricated chemical plants powered by the likes of repurposed car engines. Its modular systems convert methane captured from landfills and other sources into energy-dense liquid methanol on-site, making it easier to transport to customers. On Tuesday, the company announced $22 million in new funding — an undisclosed mix of Series A equity and non-dilutive federal and state grants — to build its first commercial-scale system at a landfill near Houston, in partnership with biogas company Montauk Renewables.
The approach aims to solve a persistent logistics problem. Economics dictate that commodity producers typically locate near a high-volume source of feedstock or a pipeline that can deliver it. But for captured methane — a potential feedstock for lower-carbon fuels, chemicals, and fertilizers — that’s often not an option. The potent greenhouse gas escapes from geographically dispersed landfills, farms, and wastewater treatment plants, many of which are too small to support a large gas-to-liquids facility and too far from existing pipelines. Trucking the gas to a centralized plant is generally prohibitively expensive, often leaving operators to either flare it or let it escape unabated.
“We are really kind of burning money, creating a lot of emissions when we could be capturing this and making high-value products,” Emmanuel Kasseris, Emvolon’s CEO, told me in an August conversation about the company’s technology, which it spun out of MIT.
“We really try to flip the script completely,” Kasseris said of the startup’s modular approach. Rather than one large facility, the company aims to produce “a few tons to maybe tens of tons per day” of methanol for the $40 billion global market. For comparison, conventional gas-to-liquid facilities can produce hundreds of times more product daily.
Emvolon’s technology is “engine agnostic,” running on repurposed engines from used cars and diesel generators as well as new builds modified for the startup’s purposes. The engines take in captured methane from landfills, farms, or gas-flaring sites. But instead of burning the fuel completely like a standard combustion engine, Emvolon limits the oxygen supply, triggering only partial combustion of the methane to produce a mixture of hydrogen and carbon monoxide known as syngas. The company then feeds that mixture into a conventional reactor, where a catalyst converts it into liquid methanol that can be shipped in standard tanker trucks.
The process requires relatively few modifications to standard internal combustion engines, Kasseris told me, thereby bringing the economics of mass production to small-scale chemical production. “You’re taking something that comes from an assembly line, you repurpose it — changing sensors, controls, simple things that require a lot of [intellectual property] but are not expensive — and you build the plant around it,” he explained. The goal is to offer customers a four-year payback period sans low-carbon fuel subsidies.
Emvolon is now attempting to push that logic a step further. For the second stage of the conversion process, the company is working to swap out its conventional reactor with another modified engine in order to “replace even more one-off process equipment” with mass-produced components. The Department of Energy’s Advanced Research Projects Agency–Energy awarded Emvolon a $2.3 million grant to develop this part of its system.
But the startup doesn’t need to have this additional piece of technology dialed in to start securing customers. In August, global commodities merchant Freepoint Commodities signed on as the startup’s primary buyer, securing priority rights to purchase at least $450 million worth of Emvolon’s biomethanol for use across maritime shipping, aviation, heavy transport, and specialty chemicals. The agreement also gives Freepoint priority rights to invest in or lend to future Emvolon projects, a provision Kasseris described as the anchor for the startup’s project financing platform.
The company’s first commercial projects are designed to produce up to 50,000 metric tons of biomethanol annually across multiple sites, with the Freepoint agreement structured to scale that output to 300,000 metric tons per year. Because each plant should cost only “a few million dollars,” Kasseris said, the company can spread out its risk rather than bet on “the half a billion dollar e-fuels plant” common to the alternative fuels industry. If one plant runs into trouble, the setback should be manageable, and the company can keep churning out and deploying its modular units elsewhere.
“This is great for scaling,” Kasseris told me. “It’s just very different. It’s just more boxes.”
