About this map

The Kashunuk River meanders across the northern reaches of this coastal Alaskan landscape, defining a complex delta environment where water and land are nearly indistinguishable. Mapping conducted by the Army Map Service in the early 1950s reveals a wilderness dominated by intricate hydraulic networks, including the Manokinak River and the significant basin of Nuigalak Lake. The terrain is remarkably flat, with Kochilagok Hill providing one of the few prominent topographic markers in an area otherwise characterized by sweeping waterways like Cross Slough and Nungatak.

This survey reflects a period when the Bureau of Land Management was predetermining land lines for unsurveyed territory using photogrammetric methods. The absence of permanent settlements or roads at this date underscores the remote nature of the region, where seasonal movement and water transport likely dictated human activity. Researchers can trace the exact courses of Wrong Creek and various unnamed sloughs as they existed before decades of natural hydrological shifts.
