1963 Map of Irish Mountain

About this map

The high-elevation divide of the Cascade Range defines this 1963 survey, where the Lane Co Deschutes Co boundary follows the crest between the Willamette National Forest and Deschutes National Forest. This alpine landscape is characterized by a dense concentration of glacial lakes, including McFarland Lake in the north and the smaller Stormy Lake and Jezebel Lake tucked beneath the peaks. The presence of the Oregon Skyline Trail and Skyline Trail indicates the importance of backcountry recreation during this era, connecting remote sites like the Irish Lake Campground. Peaks such as Irish Mountain, Cultus Mountain, and Pillar Peak overlook a terrain dotted with dozens of named water bodies, from Lady Lake to Simon Lake, highlighting the complex hydrology of the volcanic plateau.
