1956 Map of Diamond Lake

About this map

Diamond Lake serves as the central hub of this 1956 mid-century survey, surrounded by the high peaks of the Cascade Range and a network of Forest Service infrastructure. The map documents the established recreational and management presence in the area, featuring the Diamond Lake Guard Sta, a State Fish Hatchery, and multiple campsites like White Fir Forest Camp. To the south, the terrain transforms into the stark Pumice Desert within the northern boundary of Crater Lake National Park, marked by the North Entrance. The landscape is dominated by volcanic features, including the jagged spires of Mt Thielsen and the broad profile of Mt Bailey. A complex system of trails, including the Oregon Skyline Trail and Pacific Crest Trail, provides a detailed record of high-country transit before modern road expansions altered the wilderness character.
