About this map

Braided river systems and glacial meltwaters define the interior Alaskan landscape in this remote section of the Yukon-Koyukuk region. The Tonzona River skirts the northeastern corner of the map, while its tributary, the Little Tonzona River, cuts across the southwestern reaches. Central to this survey is the drainage of Pingston Creek, which winds through the central corridor alongside the distinct channels of Jones Creek and North Fork Jones Creek. These waterways provide critical orientation in a wilderness marked by significant elevation changes, ranging from the lowlands of the Clear Fork to the high ridges of the northeastern mountains. The absence of roads or permanent structures underscores the isolation of this terrain, reflecting the character of the Alaska Range's northern foothills in the early twenty-first century.
