Growing up in the East Bay as the son of an astrophysicist and a psychologist, Obi Kaufmann spent most of high school practicing calculus and breaking away on weekends to scramble around Mount Diablo and map its creeks, oak forests, and sage mazes. Into adulthood, he would regularly journey into the mountains, spending more summer nights without a roof than with one. For Kaufmann, the epic narrative of the California backcountry holds enough art, science, mythology, and language for a hundred field atlases to come. He is the author of the award-winning California Field Atlas and The State of Water. His latest book is The Forests of California. When he is not backpacking, you can find the painter-poet at his desk in Oakland, posting @coyotethunder #trailpaintings on social media. His website is coyoteandthunder.com.
