It forms the southeastern extremity of the Doyran Heights, and overlooks Rutford Ice Stream to the east and Obelya Glacier to the west.

The feature was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1957–59, and was named by the Advisory Committee on Antarctic Names for William F. Johnson, a meteorologist at South Pole Station in 1957.^[1]
