About this map

The Isahultila Mountains anchor the southern boundary of this interior Alaskan landscape, a region defined by complex drainage systems and significant elevation changes. Centrally located, Lake Tokhaklanten sits within a broad basin, fed and drained by unnamed tributaries that eventually contribute to the Batza River in the southeast. The terrain rises sharply toward the west at Bakatigikh Mountain, while the northeast is dominated by the Hokotena Hills.

Mapping of this area reflects a mid-1970s aerial perspective, capturing a wilderness devoid of roads or permanent settlements. Significant waterways like Koskatantna Creek and Baathbakdizuni Creek dictate the topography, illustrating the natural hydrological patterns of the Yukon-Koyukuk region before any modern industrial footprint. Small features such as Lake Tunilkhanten and Hughes Creek provide specific landmarks for navigators and researchers studying the subarctic environment.
