2019 Map of Ruby D-4 SE
USGS Topo · Published 2019About this map
Grass Lake lies at the heart of this Yukon-Koyukuk landscape, where complex wetland patterns and small ponds dominate the central terrain. To the north, the winding course of Twin Slough indicates the presence of a dynamic river system, while Deer Cr cuts through the western sections. The map reveals the intricate drainage and muskeg typical of this Alaskan region, showcasing a topography defined more by water and marsh than by human development. Surveyed in the early twenty-first century, the sheet documents the natural state of these watersheds across several township boundaries, including t7s r21e and t8s r21e, providing a baseline for environmental study and navigational reference in an area devoid of modern road networks.
