About this map

The South Fork Kuskokwim River carves through this portion of the interior, meeting the Tatina River amidst the high-elevation terrain of the Alaska Range. The landscape is dominated by the massive formations of the Teocalli Mountains to the north and the Terra Cotta Mountains to the southwest, creating a corridor of drainage for glacial tributaries including Lynx Cr and Dalzell Cr. This remote area, mapped in the early twenty-first century, represents a critical intersection of river valleys and mountain passes. The presence of the Tatitna Airport near the confluence of the major rivers highlights the reliance on air travel for access in a region devoid of established road networks, serving as a vital link for the Yukon-Koyukuk Census Area.
