The Botanists at Crater Lake National Park by Elizabeth L. Horn

One notable effort in the 1950s was the work by Charles Yocom (1914-1985), a seasonal naturalist in 1951 and 1952. A skilled illustrator who learned his trade drawing plants used by waterfowl, he developed an interest in the Park’s shrubs. He left an illustrated manuscript with the Park which was later published by the Crater Lake Natural History Association (Yocom 1964). He went on to illustrate other popular publications and became a professor of wildlife at Humboldt State College (N. Simmons, pers. comm.).
