1956 Map of Black River A-1

USGS Topo · Published 1973

About this map

Grayling Fork Black River cuts a winding path across this interior Alaskan wilderness, defining a landscape dominated by expansive wetlands and isolated summits. The drainage network is further defined by the convergence of Bull Creek and Tikan Creek, where the terrain transitions from low-lying swamps to prominent high points like Steamboat Mountain and Midnight Hill. This 1956 survey captures a remote frontier along the Alaska Yukon border, where the land remains largely unorganized and unsurveyed. The topography reflects a pristine subarctic environment, with the United States Canada boundary line serving as the primary man-made feature in an area otherwise shaped by hydraulic patterns and glacial relief.
