The Watson Escarpment (86°0′S 145°0′W) is a major escarpment in the Queen Maud Mountains, trending northward along the east margin of Scott Glacier, then eastward to Reedy Glacier where it turns southward along the glacier's west side. Somewhat arcuate, the escarpment is nearly 100 nautical miles (180 km) long, rises 3,550 m above sea level, and 1,000 to 1,500 m above the adjacent terrain.

Discovery and name

The north-central part of the escarpment was observed from a vantage point on Supporting Party Mountain and was partially mapped in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould. The escarpment was more closely observed in December 1934 by the Second Byrd Antarctic Expedition geological party under Quin Blackburn, and was named by Richard E. Byrd in honor of Thomas J. Watson, American business executive, a patron of this expedition. The escarpment was mapped in detail by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1960-64.
