2017 Map of Chandalar B-3 SW

About this map

Middle Fork Chandalar River dominates the southeastern portion of this landscape in the Yukon-Koyukuk region. In this 2017 study, the river's meandering course and braided channels reveal a complex hydrologic pattern beneath high terrain. Siwash Pass provides a significant transit point through the central highlands, marking a break between the ridges that separate the primary watersheds. To the north and east, smaller drainage systems like Big Creek and Agitator Cr carve into the slopes of the Chandalar country. The map clearly delineates the township and range lines, including t29n r4w and t28n r3w, which provide a formal grid over this interior Alaskan wilderness, where the topography rises sharply from the river valley toward the northern peaks.
