1989 Map of Polallie Ridge

USGS Topo · Published 1989

About this map

The Alpine Lakes Wilderness Area dominates this high-altitude terrain, showcasing a network of glacial lakes and dramatic mountain crests within the Wenatchee National Forest. This late-1980s data highlights the remote geography of the Cascades, where the Cooper River and Kachess River drain the high snowmelt from peaks like Island Mountain and Cone Mountain. Navigational points for backcountry travelers are marked at Waptus Pass and Cooper Pass, connecting isolated water bodies such as Waptus Lake and Pete Lake. The southern edge of the sheet reaches the northern tip of Little Kachess Lake, a vital reservoir point. The naming of prominent features like Polallie Ridge and Chikamin Ridge reflects the deep regional history of the central Washington mountains, while No Name Ridge suggests the wild, unpeopled character of the landscape at the time of the survey.
