Innoko National Wildlife Refuge dominates this section of the Yukon-Koyukuk region, where the landscape is defined by the shifting drainages and complex wetland systems of the Alaska interior. The map reveals a transition from the lower riparian zones into the uplifted terrain marked by the t19s r3e and t19s r4e survey boundaries. The absence of named settlements or infrastructure underscores the preserved wilderness character of the refuge during this 2017 survey. The contour lines trace the significant elevation gains that rise from the river valleys, providing a detailed record of the physical geography and hydrological patterns that dictate movement and habitat within this protected corridor.
