1954 Map of Ophir D-4

About this map

Tolat Hills dominate the northern landscape of this interior Alaska region, rising above a vast network of wetlands and meandering waterways. The Dishkaket River winds through the southern half of the territory, defined by intricate oxbows and seasonal flood patterns that speak to the ever-shifting nature of the terrain. The hydrological complexity is further detailed by the confluence of the Little Mud River and Gatalee Creek, which drain the surrounding lowlands. Based on aerial photography from 1953, the map illustrates an era before significant modern infrastructure, focusing entirely on the natural landforms and traditional water routes used for navigation and subsistence in the Yukon-Koyukuk region.
