Tetthajik Cr winds through this high-latitude terrain within the t22n r31e and t22n r30e townships, where the topography reaches elevations above 2,600 feet. This 2018 survey documents a remote portion of the Yukon-Koyukuk Census Area directly abutting the international boundary between the United States of America and Canada. The landscape is defined by its drainage patterns and the stark absence of human infrastructure, characteristic of the interior Alaskan wilderness. Local hydrography and elevation contours provide the primary points of orientation for this quadrangle, which sits at the far eastern edge of the state.
