About this map

Mt Jefferson Primitive Area dominates this high-altitude landscape, centered on the towering volcanic peaks and glacial headwaters of the Cascade Range. Surveyed in the late 1920s, the map documents a wilderness managed through an extensive network of remote stations, including the Trout Lake Ranger Sta, Lemiti Ranger Sta, and Old Mill Ranger Sta. These outposts supported the early forest service infrastructure that predated modern road access into the deep backcountry of the Mount Hood National Forest and Santiam National Forest.

Recreational and geothermal features are notable, with the Breitenbush Hot Sprs and other Hot Springs marking significant geological activity. Early backcountry travel is traced via the Skyline Trail and Lemiti Trail, which connect isolated meadows like Jefferson Park and Pigeon Prairies. The drainage patterns of the Warm Springs River and Collawash River define the sharp relief of the area, while landmarks such as Boca Cave and several lookout towers like Hawk Mtn Lookout emphasize the era's focus on fire surveillance and resource management.
