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.

A small but growing share of counties are targeting data centers, solar farms, and battery storage systems at the same time.
I’ve got an update for you on the data center backlash — and what it could mean for the governor’s race in Wisconsin, one of the country’s most important state-level battles in the upcoming midterms.
Last week, I wrote about how the Republican congressman and Wisconsin gubernatorial candidate Tom Tiffany was trying to turn the data center issue into a kind of trojan horse for slowing down renewables. Tiffany claimed to be anti-data-center, but he was really looking to apply new and stricter rules to clean energy development, as well.
Over the weekend, Tiffany said the quiet part loud. “David Crowley wants to cover our farmland with industrial-scale wind, solar, and data centers,” he posted on X. (He also started calling his opponent “Data Center David Crowley.”) Tiffany vowed to “protect Wisconsin farmland,” picking up on the idea — already used by the Trump administration to stymie solar development — that renewables threaten the integrity of agricultural land.
Now Crowley isn’t nearly as pro-data-center as Tiffany claims, although he has said the computing facilities should run on 100% clean energy. Yet Tiffany's accusation made me curious: How many local governments now see data centers and renewables as a package deal — and a farmland-threatening incursion that should be blocked? Back in March, my colleague Jael Holzman has covered how data centers are turning Americans against renewables. Are we seeing that on the ground?
Our market intelligence service Heatmap Pro tracks local laws affecting clean energy, batteries, and data centers. I asked the Pro team to look at how many local governments have now banned all three types of infrastructure — communities with what you might call a “none of the above” policy.
There’s mostly good news in the results for renewables advocates. The number of towns and counties that have blocked data centers, solar, and batteries remains small. As of late last week, 21 counties across the country have an active restriction or moratorium on solar, batteries, and data centers combined.
Another 10 counties have banned either data centers and solar, or data centers and batteries, but not all three. Six cities or municipalities have placed combined restrictions on the technologies nationwide.
The bad news: The number is growing fast. Most of these “none-of-the-above” restrictions were passed in 2026, and the overwhelming majority are in the rural Midwest and Great Plains. Kansas, Iowa, and Indiana account for most of the moratoriums or restrictive laws.
Not all of the restrictions are new. Although most of these multi-technology restrictions get passed at the same time, a handful of counties blocked solar and batteries first, then tacked on data centers later. Dickinson County, Kansas, for instance, has long blocked solar and batteries. But this spring, as the data center boom came along, the county’s leaders extended that moratorium to apply to data centers and all forms of energy development — including natural gas.
Overall, the scale of the trend remains small. Less than 10% of data center restrictions nationwide also target clean energy. That’s good news for renewable developers because the number of data center ordinances is surging. More than 530 data center restrictions are now on the books nationwide, and most restrictions have come in the past 12 months.
And what about the Wisconsin election? As of right now, only one county in America’s Dairyland has restricted data centers and batteries together. None have restricted solar, wind, and batteries. But Tiffany does seem to be tapping into a much larger zeitgeist. When you look at the stated reasons why communities nationwide are adopting these policies, farmland protection ranks high on the list. When it comes to permitting politics, in other words, farmland looks like the next frontier.
There are lots of reasons why that might seem like a good idea, but I urge you to learn from my mistakes.
All I wanted was to drive an electric car to the solar eclipse. But after the third consecutive charging port RFID reader wouldn’t accept my credit card and finding that the employees inside the attached Spanish hotel restaurant mostly didn’t speak English, I began to feel as though, just maybe, this hadn’t been my best idea.
Opting for an EV as a rental car can be an attractive proposition. For a longtime electric driver like me, it’s the opportunity to avoid car emissions even when on holiday, and to try out the experience in another country. For others, it could be a way to save money while on vacation in countries with even more expensive gasoline than America’s, or perhaps to try out electric driving before taking the plunge on buying an EV back home.
My advice, though? Don’t — at least not yet. The reason is that road-tripping on vacation is not only different from the driving you do back home, it’s also the worst kind for using an EV, especially for a newbie. The experience might lead you to believe, incorrectly, that the EV experience is just like this.
I admit, I had high hopes. Europe as a whole is far ahead of the United States in EV adoption, and its denser built environment means fewer long, open expanses between the kinds of cities that would have charging stations. Spain isn’t nearly as far along with EVs as the Scandinavian or the low countries, where electric cars are already a majority of cars on the road, or nearly there. But it is ahead of the U.S. So I figured driving around the country to see the total solar eclipse in a Peugeot E-5008 electric SUV would be a manageable task.
The first problem is time. Here in California, I’ve come to terms with the fact that driving long distances in an EV adds minutes. There’s simply no way to replicate the five-minute pump-and-go gas station stop, but when it comes to dealing with the slog of freeway travel from L.A. to the Bay Area, for example, I’ve come to enjoy taking a longer charging stop to breathe as opposed to making the best possible time on a car trip. On vacation, though, there’s no time to lose.
And it’s not just charging itself that takes time. Unless you rent a Tesla and enjoy the seamless experience of its Superchargers, you’re stuck with the same annoyances that have vexed so many EV early adopters in the U.S.: busted chargers, hit-or-miss credit card readers, and juggling a variety of phone apps to interact with all the various brands of charging stations one might encounter. It’s also, frankly, just mentally taxing to think about all this in a new country and a new car, the very opposite of what most people seek on holiday.
Driving abroad intensifies these grievances. In just five days of driving around Spain, I racked up five new phone apps dedicated to charging the car on different networks. (Electromaps! Movilidad! PowerGo! EnelEnergy! Zunder!). Sometimes this was out of desperation: I parked, plugged, and scanned multiple credit cards that the machine would not accept, finding pay-by-phone to be the only way to activate the machine. Of course, signing up for a new app is a 10-minute process that involves typing in endless fields of personal information just to add a few kilowatt-hours to one’s car battery. Not great when you’re already running behind, and doubly problematic if you had no or little cell service abroad and couldn’t download the necessary app at that moment. (Death to walled-off apps.)
Those chargers that did work typically ran far below their stated capacity, in the range of 70 kilowatts to 90 kilowatts of charging speed as opposed to the 180 kilowatts or 350 kilowatts they were rated to deliver. And when plugs are scarce, you have to take what you can get in terms of speed and amenities. I was overjoyed to find one that worked without much hassle in Basque Country — even though I had to ask one of the gas station employees to move her Volkswagen Passat that was ICEing a charger, and encountered an industrial stench from nearby petroleum production so strong I nearly vomited when I got out of the car.
The EV culture can be different, too. I’d hoped to charge at the plugs located in the parking garage of my hotel in Bilbao, Spain, but arrived home too late after eclipse traveling and found the lot full and locked. The nearby underground structure had plenty of charging spaces, but those were bring-your-own-cable chargers — something common in Europe that’s only now coming to the United States.
Despite the difficulties, the trip went off. We saw the spiritual experience of the eclipse through the cloudless skies of Burgos; we traveled around northern Spain without once having to buy gasoline at European prices. And while an inconvenient experience like this might be enough to dissuade someone from ever taking a chance on EVs again, it shouldn’t.
There’s a dichotomy in the electric car experience I’ve talked about ad nauseum. As detractors say, taking long road trips can be kind of annoying, and those annoyances run deeper in unfamiliar territory. But most of us don’t drive like we’re on vacation most of the time. We do our driving close to home, where electric cars are a better and more convenient experience if you can do much of your charging at home or work. Public charging still takes time. But in your own city and state, you already know the nearby ones you like and have all the necessary apps downloaded and filled out.
A more seamless time is coming, when charging stations are abundant everywhere and a simple, idiot-proof interface for plugging in is the standard. Until then, you’ll probably have a more relaxing vacation burning fossil fuels. Just don’t let that stop you from buying an EV.
Current conditions: Tropical Storm Moke sideswiped Hawaii yesterday just weeks after a weakened Hurricane Lala became the first major storm to hit the Big Island in decades • On the western fringe of the United States’ Pacific borders, Typhoon Saudel struck Guam and the Northern Mariana Islands over the weekend, bringing heavy rain and flooding • Temperatures in Khorramshahr, on Iran’s border with Iraq, are topping 118 degrees Fahrenheit, rendering the southwestern port city the hottest place on Earth.
With water levels in reservoirs across the American West at record lows, the Trump administration has directed Arizona, California, and Nevada to cut back on how much water they use from the Colorado River over the next two years. On Friday, the Department of the Interior imposed the reductions via a series of documents detailing a two-year and a 10-year plan to salvage the supplies from the drought-stricken river fed by snowmelt from Colorado’s stretch of the Rocky Mountains. As climate change has shifted snow patterns, levels on the river have dropped. Yet the seven states that depend on the water — the aforementioned three in the Lower Basin, and Colorado, New Mexico, Utah, and Wyoming in the Upper Basin — could not come to agreement among themselves on how to divvy up the dwindling supply. Instead, the Interior Department came up with a proposal that forced the Lower Basin states to pare back first. As you may recall, Arizona’s Democratic governor called the cuts “draconian” when the administration released its proposal in early August. The plan, which imposes short-term cuts while leaving a larger split for later, sets the stage for what E&E News predicted would be “a behemoth legal fight.”
When the Department of Energy announced a review last year of droves of grants the Biden administration had given for clean industrial projects, the nation’s leading green steel project appeared on the chopping block. Cleveland-Cliffs, the steel giant based in Vice President JD Vance’s hometown in Ohio, said it was renegotiating the $500 million grant that was supposed to fund construction of a modern, integrated mill that could increase U.S. steel production and allow the country to compete with China in selling lower-carbon material to Europe. More than a year later, the deal has finally been renegotiated. As expected, the money will now go instead toward upgrading a coal-fired blast furnace at the Middletown Works plant, Canary Media reported on Friday. Never mind the fact that Congress promulgated the money specifically for lower-carbon steel, making the shift “possibly illegal,” as my colleague Emily Pontecorvo reported last year.
Congestion costs on PJM Interconnection skyrocketed 43% to $6 billion during the first half of this year, up from $2.1 billion during the same period of 2025. That’s according to the grid’s independent watchdog, which last week warned that bottlenecks on high-voltage transmission lines during high-stress events such as storms or heat waves were now what Reuters put bluntly as “the single biggest driver of the increase in soaring wholesale electricity costs.” Across the U.S., July’s electricity bills were, in the frank words of Heatmap’s Matthew Zeitlin, “higher than ever.”

Last week, the uranium miner Ur-Energy sent the first shipment from its mine in Wyoming, World Nuclear News reported Friday. That same day, the American subsidiary of the European uranium giant Urenco broke ground on its latest facility in the U.S., NucNet reported. Downstream, meanwhile, Standard Nuclear — a fuel manufacturer specializing in extra-expensive but extra-safe ceramic-coated fuel pellets called TRISO, which I have written about previously— just cut another deal with a major vendor.
I have a confession. Nearly a decade ago, I sat at my sister’s kitchen counter in Massachusetts after she gave birth to my niece, trying to write about the latest technology to come out from Tesla. Not yet burdened by its billionaire chief executive’s political baggage, the company was largely seen at the time as subverting preconceptions about the popularity of electric vehicles. Tesla’s erstwhile absorption of Musk’s former solar manufacturer, Solar City, only cemented the company’s status as an industry leader in producing and deploying panels domestically. The conventional wisdom, at least among some industry analysts at the time, was that any bet against Tesla was an ill-advised gamble against the lucky Mr. Musk. So, I wrote about it as a breakthrough. But the solar-generating roof tiles the company unveiled that fall when I was in New England turned out to be little more than a passing fantasy. Now Electrek has reported that the company plans to discontinue the product.

Say what you will about Spain’s solar records or America’s gas surge, nothing quite matches the enormous surge of power that is a new hydroelectric station. This week, Tanzania christened its largest-ever hydroelectric station, the Julius Nyerere Hydropower Dam, named for the country’s revolutionary first prime minister after independence. Mwananchi, the country’s largest newspaper, said the plant’s launch “opened a new chapter in Tanzania’s energy sector.”
