2019 Map of Ruby A-5 NW
USGS Topo · Published 2019About this map
Sulatna Crossing marks a rare point of human infrastructure in this remote stretch of the Alaska interior, situated where the Ruby-Poorman Road (Extension) intersects the meandering Sulatna River. The landscape is defined by the heavy winding of water through low-lying flats, flanked by elevated features like Sulatna Bluff and Tamarack Bluff. This 2019 survey documents a complex network of drainage basins, including Ophir Cr, Foley Cr, and Spangle Cr, which feed into the primary river system. The presence of the road extension highlights the ongoing significance of the Ruby-Poorman corridor, a vital link for mining and transit in the Yukon-Koyukuk Census Area. This map provides a clear record of the area's hydrology and the fragile reach of overland travel through the Alaskan wilderness.
