2018 Map of Sumdum A-2 SW

About this map

Baird Glacier and Patterson Glacier dominate the northern and eastern reaches of this high-altitude landscape in the Tongass National Forest. The map documents a classic glacial environment where drainage systems like Cascade Cr and Scenery Creek are fed by permanent ice fields. The central valley is anchored by Scenery Lake, a major hydrologic feature nestled below the southern heights of the Cosmos Range. This 2018 survey provides a precise record of ice margins and alpine hydrology, illustrating the complex relationship between active glaciation and the carved valleys of southeastern Alaska.
