Obi KaufmannGrowing up in the East Bay as the son of an astrophysicist and a psychologist, Obi Kaufmann spent most of his high school practicing calculus and breaking away on weekends to scramble around Mount Diablo and map its creeks, oak forests, and sage maze. Into adulthood, he would regularly journey into the mountains, spending more summer nights without a roof than with one. He is the author of The California Field Atlas (2017, #1 San Francisco Chronicle Best Seller), The State of Water: Understanding California's Most Precious Natural Resource (2019), and The Forests of California: A California Field Atlas (2020), all published by Heyday. When he is not backpacking, you can find the painter-poet at home in the East Bay, posting trail paintings at his handle @coyotethunder on Instagram. His website is coyoteandthunder.com.
