2021 Map of Yakutat C-3 SW

About this map

The Saint Elias Mountains define the high-altitude geography of this 2021 survey, where the massive South Glacier and Moser Glacier flow through the interior of the Tongass National Forest. This sub-quadrangle records a landscape of extreme topographic relief, transitioning from icy peaks like Slate Peak and Crescent Mtn to the drainage basins of the Ahrnklin River. The hydrological patterns here are particularly distinct, with Moser Cr and Miller Cr carving through the glaciated terrain south of the major ice fields. As a modern record of the Alaska Yakutat region, the map documents the relationship between permanent ice, seasonal snowfields, and the emerging river systems that feed into the Gulf of Alaska coastal plains.
