About this map

The Yukon River carves a massive course across this interior landscape, defining the transition from the high Kokrines Hills in the north to the low-lying wetlands of the Junekaket Creek basin. Near the settlement of Kokrines, the river is divided by a series of significant landforms including Hardluck Island and Mickey Island. A notable artifact of early frontier communication, an Abandoned Telegraph Line, follows the northern riverbank, reflecting the region's historical reliance on this corridor for connectivity.

Thermal activity is evident at Horner Hot Springs (Alex's), located near the southern bank. Below the White Cliffs, the river floodplain becomes a complex network of secondary channels like Hot Springs Slough and Junekaket Slough, which weave around Ham Island and Dasha Island. This dense system of sloughs and lakes, such as Grass Lake, characterizes a wilderness shaped by seasonal water movement and shifting island bars.
