In September, as wildfire raged in Medicine Bow National Forest, Karen Vaughan watched smoke billow in a choked-off Wyoming sky. The sun was reduced to a matte neon-pink disc behind the haze, and Vaughan worried about her research site in the burning mountains. One of her graduate students still had one more day of fieldwork to complete, and the roads would soon be closed, if they weren’t already. Vaughan’s family—her husband and two kids—were outside too, watching as a light gray layer of wind-blown ash settled onto the landscape. The ash and vivid colors sparked something in Vaughan, who continually sought new inspiration for the paint she makes. She began dashing around, scraping the sediment from every flat surface and encouraging her kids to help collect the fine powder. She decided to incorporate that ash into watercolor pigments with hues reflecting the fire, indelibly preserving the moment. The small batch of paints, distributed to friends and local artists, would be used to create depictions of the destructive forces that allowed their creation in the first place. “You’re breathing that air, even in your house, and you look outside and see that weird orange glow,” says Vaughan. “You couldn’t help but be a part of that.”
A soil scientist and a professor at the University of Wyoming, Vaughan sees a lot more soils than the average person, and certainly knows them more intimately. Over many years spent examining them, she has come to appreciate their natural beauty and immense variability. Two years ago, she began channeling that appreciation into a product she could share with the world, turning the soils she loved into watercolor pigments. Now, she and her collaborator, Yamina Pressler, a soil scientist at California Polytechnic University, use soils to make pigments and paintings, bridging the gap between science and art. By sharing both their creative processes and scientific knowledge on social media and connecting with artists, scientists and the public, they aim to make soil education entertaining.
