2017 Map of McCarthy D-1 SW

About this map

The Wrangell-Saint Elias National Preserve encompasses most of this landscape, where the elevation rises steeply toward the northern boundary. Glacial influence is evident in the alignment of the waterways, particularly the large basin containing Rock Lake. Fed by Young Cr from the west, this water body sits within a high-altitude valley defined by sharp ridgelines. To the northeast, the smaller Ptarmigan Lake is tucked between ridges, while Francis Cr drains the northern slopes. The map illustrates a transitional sub-arctic environment, showing the fine-grained topographic detail of the alpine terrain and the drainage patterns that characterize this remote portion of the Chugach Mountains region before the landscape reaches higher glacial peaks.
