1958 Map of Tyonek B-5

USGS Topo · Published 1971

About this map

Beluga Lake dominates the central landscape of this wilderness region, marking a significant hydrological divide at the border of the Matanuska-Susitna Borough and the Kenai Peninsula Borough. Massive ice fields, including the Triumvirate Glacier and Capps Glacier, define the western edge of the terrain, with numerous Crevasses noted across their frozen surfaces. The map documents a complex network of glacial runoff and mountain streams, where the Chichantna River and Coal Creek drain toward the lowlands. The presence of Strandline Lake and Coal Creek Lake in the north suggests the dynamic nature of these glacial margins during the mid-century. While largely devoid of permanent human settlements, the survey provides a precise record of the natural topography and unsurveyed land lines predetermined by the Bureau of Land Management.
