2016 Map of Valdez B-3 NW

About this map

Tonsina and the corridor of the Richardson Highway anchor this 2016 survey of the Alaskan interior. The landscape is defined by its complex drainage network, where the Little Tonsina River and Uranatina River flow through high-elevation terrain. The presence of the highway follows the natural path adjacent to the Tiekel River, illustrating the historical reliance on river valleys for infrastructure in this part of the Unorganized Borough. Tributaries such as Bernard Cr, Ernestine Cr, and Mosquito Cr branch across the topographic contours, revealing the hydraulic patterns that have shaped the region's geography and limited settlement primarily to the road corridor.
