About this map

Mastodon Dome serves as the topographic anchor for this remote section of the Yukon-Koyukuk region, where 1950s mining activity is etched into the high country. The Steese Highway cuts across the northwest corner, providing the primary access through Eagle Summit. Below these heights, numerous Placer Mine operations are noted along the drainages of Independence Creek and Mastodon Creek, indicating a landscape shaped by gold exploration.

The drainage network is complex, characterized by narrow gulches and "pups" like Bender Pup and Forty-mile Pup that feed into larger arteries such as Harrison Creek. In the south, the broad, meandering path of Birch Creek dominates the valley floor, contrasted against the high-elevation survey markers like VABM 3832 Pend. The presence of small outposts like Berry Camp and isolated Cabin sites suggests the seasonal, industrious nature of the territory during this era of Alaskan interior development.
