1958 Map of Tyonek D-8

USGS Topo · Published 1963

About this map

The Skwentna River dominates this mid-century survey, its braided channels carving through a landscape defined by glacial movements and high peaks. This 1958 field-annotated sheet captures a transitional era of Alaskan surveying where photogrammetric methods from 1957 aerial photography were used to map areas previously marked as unsurveyed by the Bureau of Land Management. Significant ice masses like Stoney Glacier and the Black and Tan Glacier feed into a network of drainages including Muddy Creek and Black and Tan Creek. The terrain is anchored by several prominent summits, including Mount Estelle, Cathedral Mountain, and Mount Stoney, which tower over Portage Pass. This map serves as a primary record of the Seward Meridian's drainage patterns and topographic elevations before later environmental changes altered these alpine and glacial features.
