Hello, This is a rock outcropping from a glacier known throughout the North as a "Nunatak". Our family, under Don Sheldon, mapped the entire Alaska range and secured the rock outcropping in 1953, with a land patent allowed in 1971. It is known as Sheldon Nunatak. The entire surrounding area is named the Don Sheldon Amphitheater also after Don Sheldon. This name was indexed by the US Government in 1975. I can provide the US Board on Geographic Names documentation, but dont see how to here.
