2018 Map of Black River A-1 NE

USGS Topo · Published 2018

About this map

Grayling Fork Black River meanders across this northern landscape near the international border, defining the drainage patterns of the eastern Yukon-Koyukuk region. This 2018 survey by the U.S. Geological Survey illustrates the transition between higher elevations and the winding watercourses that characterize this wilderness corridor. The northern reaches are shaped by the flow of Tikan Cr, which cuts through the mountainous terrain before joining larger systems to the west. Positioned directly against the boundary of Canada and the United States of America, the map offers a clear view of the topographic contours that define this remote section of the interior. The survey provides a precise record of the land's natural geometry, highlighting the isolation and scale of the river valleys in an area devoid of permanent modern settlements or infrastructure.
