About this map

Lost River and Wood Cr define the primary drainage patterns of this Alaskan interior terrain within the Yukon-Koyukuk Census Area. The landscape is characterized by high, rhythmic contour lines that illustrate the elevation changes between these two water bodies. This area, marked by the Public Land Survey System coordinates t16s r20e and t17s r21e, shows no established roads or settlements in this 2019 survey, reflecting the remote nature of the region. The detailed elevation data provides a clear picture of the watershed where Wood Creek and Lost River flow through the valleys, offering a distinct record of the natural topography in this part of the Ruby quadrangle.
