2017 Map of Skagway B-4 SE

USGS Topo · Published 2017

About this map

Porcupine Peak stands as a prominent landmark in this corner of the Haines Borough, where the high ridges of the Alaska Range meet a complex drainage network. The landscape is defined by the broad glacial valleys of the Tsirku River and the Takhin River, which dominate the southern portion of the survey. Numerous steep-gradient streams, including Porcupine Cr, McKinley Cr, and Cahoon Cr, carve through the mountainous terrain to feed these larger river systems. The convergence of Nugget Creek with the Tsirku River illustrates the hydrological patterns typical of this sub-arctic environment, where seasonal melt from the peaks drives the flow of Summit Cr and Cottonwood Cr toward the valley floors.
