Donnelly Dome is a summit located west of the Richardson Highway, 18 miles south of Delta Junction, Alaska. The name was established in the 1920s and derived from nearby Donnelly, Alaska, then a telegraph station. Prior to that time it was called "Delta Dome", named after the Delta River. [1]
Donnelly Dome was formed through glaciation that occurred 70,000 to 100,000 years ago. It was completely covered by the glaciers, and was considered a fleigberg, or a mountain covered in ice. [3]
The area around Donnelly Dome is owned by the United States Army as part of the Donnelly Training Area of Fort Wainwright, [4] so hikers are required to register for a Recreation Access Permit before visiting. [2]
