2019 Map of Ruby C-4 SE

About this map

The Sulatna River winds through this interior Alaskan wilderness, exhibiting a complex, meandering path that dominates the southern and eastern portions of the landscape. This 2019 survey by the U.S. Geological Survey illustrates the intricate hydrology of the Yukon-Koyukuk region, where the river's tight loops and oxbows suggest a low-gradient floodplain subject to seasonal shifts. In the southeast corner, the tributary Monzonite Cr joins the drainage system, providing a specific point of reference for researchers tracking watercourses in this undeveloped terrain. The map is primarily defined by its natural features and the established township and range lines of the Public Land Survey System, including t11s r21e and t10s r22e, which provide the only structural grid over the unpopulated expanse.
