This 2019 survey documents the hydrologic features and the Public Land Survey System grid including t30n r28w and t31n r27w. The absence of roads or structures in this area highlights the preserved character of the Alaskan wilderness within the Yukon-Koyukuk region, providing a baseline for environmental study and land management.
