The Okpilak Valley dominates this 2018 survey of Alaska's North Slope, where the drainage systems of the Okpilak River and Akutoktak River carve through high-elevation terrain. This map reveals a landscape defined by glacial and fluvial processes, centering on the prominent Okpilak Lake and the winding course of Old Man Cr in the western reaches. The absence of human infrastructure highlights the untouched character of the North Slope Borough, where land use is dictated by the natural topography and the seasonal flow of arctic waterways. For researchers of Alaskan geography, the map provides a precise look at the township and range boundaries including t1n r33e and t2n r33e, documenting the foundational survey lines of this remote northern interior.
