1959 Map of Three Sisters

USGS Topo · Published 1964

About this map

Glaciated peaks and volcanic fields define this 1959 survey of the High Cascades, where the Lane Co Deschutes Co boundary crosses the summit of the North Sister and Middle Sister. This era was critical for recreational infrastructure within the Willamette National Forest, as evidenced by the network of seasonal locations like the White Branch Youth Camp and the Devils Garden Forest Camp. The map serves as a detailed record of the mid-century wilderness before significant modern trail realignments, showcasing the original route of the Oregon Skyline Trail as it traverses the Cinder Field and skirts the Collier Glacier. High-altitude shelters such as the Sunshine Shelter and James Creek Shelter provided refuge for travelers navigating the volcanic terrain near Obsidian Cliffs and the Lava flows of the Branch. For those researching the geography of the central Oregon range, the sheet names numerous water features including Linton Lake and the Tenas Lakes.
