What began as a hobby for CU Boulder economics undergrad Lucas Gauthier came together as a photographic portfolio documenting the already-evident and potential effects of climate change

Lucas Gauthier and his family moved to Colorado when he was in 6th grade, and after a decade of fairly frequent moves—both parents were in the military—this is where everything made sense: mountains for climbing, runs for skiing, trails for hiking and rivers for rafting.

They took some convincing, but eventually his parents let him venture out on his own—forays that grew longer and longer and took him farther and farther into the Colorado wilderness.

Lucas Gauthier, a senior majoring in economics, has photographically documented his adventures in western landscapes since he was in high school.

About four or five years ago, he began taking pictures along the way, usually on his phone. The photography wasn’t the point, necessarily, “but I found that, especially in Colorado, hiking puts you in some very beautiful places,” he explains. “I hike, and the pictures happen while I’m hiking.”

A through line for what had become a large portfolio of photographs emerged in spring 2024. Gauthier, a senior majoring in economics with a focus on natural resource management, was taking , a class that requires students to complete three projects during the semester.

The first two projects were more technically focused, but the third emphasized creating something of personal value. So, Gauthier thought about all the places in Colorado that he loves, scrolling through both his memories and his photos. He realized that what began as an almost offhanded hobby was actually documenting places that would be or already were altered by climate change.

From that realization was born , a multimedia project that incorporates not only data about things like wildfire, heat wave and drought risk and their potential for significant economic impact, but makes it personal with the scenes of incomparable beauty he has witnessed and documented.

“My interest in water specifically came from my interest in hiking and skiing and an interest in all outdoor sports,” Gauthier says. “When people say there’s going to be less rain, less precipitation, that’s a big deal for me.

“I worked and lived in Breckenridge, which is a tourism-dependent area, so if there’s not enough water, that’s weeks of ski season that are lost, and there might not be a rafting season, so that’s where you start to see the overlaps between how climate change is affecting natural systems and the actual economic impacts on livelihoods.”

Capturing what he sees

“My interest in photography has been in capturing this broad swath of environments that we get to play in—as a way to memorialize the experience for myself, and also to share it with others,” Gauthier says.

He took two photography classes in high school, neither of which focused on outdoor or landscape photography, “but I do think those gave me a good idea for how to compose photos and set them up, how to look for different lighting and visual elements,” he says. “They got me in the mindset of thinking, ‘This is something that strikes me, and I’ll see if I can frame it in way that works with what I want to capture.’”

Gauthier was also in high school when he began tackling ever-more-ambitious climbs and started working his way through Colorado’s 58 fourteeners, a goal he completed over the summer. Of those 58, he climbed at least 45 solo.

“(Climbing solo) is kind of a mix of preference and necessity,” Gauthier explains. “It’s easier when the only person you have to plan for logistically is yourself. And when you’re trying to beat lighting and thunder, it’s best to move light and fast.”

However, he never moves so fast that he can’t look around and, if he’s able, to capture what he’s seeing in a photograph. And he returns to certain favorite places, enough that he can compare them season by season or year by year.

“We’ve had a mix of good and bad snow years, but it’s been very noticeable when a particular area that usually has good (snow) coverage into May or June has already melted,” he says. “And there have been times when I’ve hiked through area and a few years later it’s a burn scar, which is a�� very visceral sense of change in the environment.

“Then there are little things like aspens are yellowing at a different date, wildflowers are blooming and stop blooming at different times. While it’s not as black and white a change, moving those transition points is definitely something that adds up in aggregate.”

Factors of climate change

Now, as he works his way through Colorado’s 100 highest peaks—he’s summited more than 80—and completes his bachelor’s degree, he still is conceptualizing what it all means. Many climate change models are forecast to take decades—if not centuries—to happen, but Gauthier is already seeing anecdotal evidence of them. What does that mean for how he exists in the outdoors and what he’s going to do after he graduates?

“I feel like there is a lot of doom and gloom, and I definitely feel that, but at the same time I am very much a person who feels like I have to say what I’m going to do about it,” he says. “With my area of emphasis in environmental economics, it’s about acknowledging that we have these issues and asking how we address them through actual, tangible means. For me, that means engaging in actual political and broader social processes. When I’m engaged in something, I feel less powerless.

“I think the main point that I wanted to communicate with this project was emphasizing how each of these different factors of climate change are integrated,” he says. “Fires affect water quality, flooding affects agriculture and all of it impacts places that I and a lot of other people love.”
