| Formed by | Glaciation |
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]
