2019 Map of Ophir D-1 SW

USGS Topo · Published 2019

About this map

The meandering Innoko River defines the southwestern corner of this interior Alaskan landscape, characterized by the low-lying wetlands and complex hydraulic patterns of the Yukon-Koyukuk region. In this unpopulated expanse, the shifting course of Slow Cr snakes through the central and northern sections of the map, illustrating the slow drainage typical of the subarctic river systems. The terrain is marked primarily by these watercourses and the established surveying boundaries of t19s r12e, t19s r13e, t20s r12e, and t20s r13e. This 2019 data release provides a precise record of the natural hydrology and elevation contours before any modern infrastructure touched this particular reach of the river basin.
