Willis Jepson’s Siskiyou Expedition

I recently came upon resource created in 1907 during a trans-Klamath adventure to explore the region and document its plants. Willis Jepson’s Siskiyou Expedition began in Yreka on July 1st and ended back in Etna on July 25th. Over that time the expedition team traveled from the eastern Klamath to the coast—and back again—using a combination of routes including poorly developed roads, the Kelsey Trail, river corridors, and portage boats guided by Karuk men. I encourage you to read more of Jepson’s journal and his colorful descriptions of the plants and places along the way. The journal offers an ecologist’s view, 110 years back, to a northwest California vastly different than today.
