1954 Map of Lake Clark D-4

About this map

The Telaquana River and Mulchatna River define the hydraulic character of this interior Alaskan landscape as it was documented in the mid-1950s. The terrain transitions from the alluvial plains of the river systems into the prominent Bonanza Hills, where numerous small lakes and ponds dot the northern reaches of the quadrangle. This 1954 survey by the Army Map Service reflects a region largely devoid of permanent roads or settlements, where navigation relied on natural landmarks such as Summit Creek and the peaks of Turk and Trail. Topographic detail captured via photogrammetric methods from 1957 aerial photography provides a precise look at the drainage patterns and elevation shifts before any modern infrastructure altered these remote watersheds.
