1954 Map of Ophir D-3

About this map

Innoko National Wildlife Refuge dominates this interior Alaska landscape, reflecting a region defined by extensive wetlands and meandering water systems. The map captures the complex drainage patterns of the Mud River and Galatea Creek as they wind through a mosaic of ponds and marshy lowlands. To the north, the Tlat Hills rise above the alluvial plain, mirrored to the south by the Wapoq Hills. These elevations provide the primary relief in an otherwise low-lying area where features like Cache Lake and the southern Wapoo Creek highlight the seasonal shift of the river network. Originally surveyed in the 1950s with later updates to include established federal boundaries, this sheet serves as a primary record of the Alaskan interior's hydrology and land-management history prior to modern development.
