The Goodpaster River winds through the heart of this interior Alaskan landscape, serving as the primary drainage for a network of tributary creeks including Sevenmile Cr and Tenmile Cr. This 2016 survey documents the remote terrain within the Unorganized Borough, where the absence of roads or permanent settlements underscores the region's wilderness character. The complex topographic contours reveal a series of elevated ridges and deep valleys that define the watershed, with Sand Cr draining the southwestern portion of the map. This study is essential for understanding the natural hydrology and elevation patterns of the Big Delta region before any potential modern development or environmental shifts.
