1954 Map of Kateel River D-1

About this map

The Koyukuk River dominates this mid-century interior landscape, winding in tight oxbows and massive loops through a dense network of sloughs and lakes. The river's meandering path has carved out significant landmasses, most notably Treat Island and Young Island, which are bounded by Treat Slough, Cutoff Slough, and Tom Cook Slough. These waterways suggest a seasonal and dynamic environment where the river channel constantly shifts, creating a labyrinth of secondary channels and wetlands.
