2017 Map of Ophir D-5 NE
USGS Topo · Published 2017About this map
Innoko National Wildlife Refuge dominates the landscape of this interior Alaskan quadrangle, encompassing a vast network of wetlands and meandering waterways. The Little Mud River and its tributary, the W Fork Little Mud River, snake through the terrain, creating complex oxbows and marshy bottomlands. This 2017 survey illustrates a wilderness nearly devoid of human infrastructure, where the natural drainage patterns of the Yukon-Koyukuk region remain the primary geographic features. The map provides precise detail for researchers studying the hydrology and protected habitats within the refuge boundaries, as the rivers shift through the low-lying interior basin.
