Best known for helping readers notice the plant life of the American Southwest, this National Park Service naturalist wrote friendly, practical guides for visitors exploring Zion, Bryce Canyon, and nearby landscapes.

by Carl E. Jepson, Leland F. (Leland Franklin) Allen
Carl E. Jepson was an American naturalist associated with the National Park Service. Reliable catalog and archive records connect him with Zion National Park, and a Wikimedia Commons category tied to his name preserves both a portrait and park photographs credited to him.
He is best remembered as co-author, with Leland F. Allen, of Wild Flowers of Zion and Bryce Canyon National Parks and Cedar Breaks National Monument, a guide published by the Zion-Bryce Natural History Association and later made available by Project Gutenberg. The book introduces visitors to the region's flowers in a clear, approachable way, reflecting the park-naturalist tradition of helping travelers see more in the landscape around them.
Other book records also link Jepson to Teton Trails: A Naturalist's Guide to Grand Teton National Park, suggesting a broader role in interpretive writing about U.S. national parks. Taken together, the surviving books and photographs show someone deeply involved in sharing the natural history of the parks with the public.
