About this map

The North Sister, Middle Sister, and South Sister anchor this volcanic landscape, surveyed in the late 1920s before modern road networks fully altered the high desert and mountain passes. The map documents an era of early fire suppression and range management, featuring isolated outposts like the Allingham Guard Station and the Black Butte Lookout. To the east, the settlement of Sisters and the historic Camp Polk area show the beginnings of community development near the Metolius Spring.

Old transport routes including the McKenzie Highway and Santiam Highway cut through the timber, while the Old Toll Station near Cache Mtn marks a remnant of earlier wagon travel. Remote work sites such as the Pole Creek Cow Camp and Trout Creek Cow Camp illustrate the seasonal grazing patterns that defined the regional economy. This study provides an exact record of the numerous high-altitude water bodies, from Suttle Lake to Clear Lake, and the primitive trails that predated the formalization of the Three Sisters Wilderness Area.
