About this map

Wrangell-Saint Elias National Preserve encompasses most of this landscape, where the transition from expansive interior wetlands to the rising foothills of the Wrangell Mountains is meticulously documented. The hydrology is dominated by the winding course of Boulder Creek, which drains through a complex network of marshes and small ponds that define the Copper River Census Area. This region, captured in a recent 2023 survey by the U.S. Geological Survey, illustrates the vast, unpopulated character of the Alaskan interior where surveying boundaries like t10n r5e and t9n r6e provide the only human-imposed structure on an otherwise wild terrain. In the southern reach of the sheet, the protected status shifts as it enters the Wrangell-St. Elias Wilderness, marking a core area of conservation and high-elevation relief.
