2021 Map of Petersburg D-2 NE
USGS Topo · Published 2021About this map
Patterson Glacier and LeConte Glacier dominate this high-altitude Alaskan landscape, where the shifting boundaries of ice meet the stony reaches of the Coast Mountains. This survey captures the interior wilderness of the Tongass National Forest as it appeared in 2021, documenting a terrain defined by massive ice fields and the high summits of the Admiral Range. The central prominence of Twin Peaks provides a geographical anchor for a region where natural drainage and glacial movement are the primary forces of change. For researchers and geologists, this map provides precise topographic data on glacier extents and mountain elevations, tracing the delicate interface between permanent ice and the surrounding forest ecology.
