About this map

The boundary between Lane and Deschutes counties runs directly through this high-elevation landscape, where the Willamette and Deschutes National Forests meet. The terrain is defined by a dense concentration of glacial lakes, from larger bodies like Cultus Lake and McFarland Lake to smaller, distinctively named waters such as Stormy Lake, Rock Rim Lake, and Jezebel Lake. Volcanic features dominate the topography, anchored by the heights of Irish Mountain, Lemish Butte, and Charlton Butte.

Outdoor recreation and early transit routes are well-documented, showing the extensive Skyline Trail as it traverses the ridgelines. The map records established backcountry sites including the Irish Lake Campground and Clover Meadow Campground, while a network of secondary paths like the Winnipee Lake Trail and Prairie Trail connect the various lake basins. This 1963 field-checked survey captures the area's primitive infrastructure before more modern developments in the Oregon Cascades.
