1990 Map of Christian B-4

USGS Topo · Published 1990

About this map

Winter Trail cuts across the southeastern landscape, serving as a primary corridor for seasonal movement through this interior Alaskan territory. This 1990 provisional edition, compiled from 1981 aerial photography, documents the hydrological systems of the Yukon-Koyukuk region, where several significant watercourses like Kocacho Creek, Marten Creek, and Timber Creek drain the upland terrain. The presence of Flooded Lake in the lower reaches suggests a dynamic environment shaped by seasonal melt and shifting drainage patterns. As a provisional map, it represents a precise moment in the ongoing efforts of the Geological Survey to document the remote northern wilderness, prioritizing topographic accuracy and waterway navigation over permanent settlement infrastructure, which remains notably absent from this portion of the Christian quadrangle.
