Watson Escarpment

Watson Escarpment (-86°N, -145°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 nmi long, rises 3,550 m above sea level, and 1,000 to 1,500 m above the adjacent terrain.

Discovery and naming
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 Byrd Antarctic Expedition geological party under Quin Blackburn, and was named by Byrd for Thomas J. Watson, American business executive, a patron of this expedition. The escarpment and its related features was mapped in detail by United States Geological Survey (USGS) from surveys and United States Navy air photos, 1960–64.

Topology
The western end of the Watson Escarpment is a massif to the northeast of the point where the Van Reeth Glacier joins the Scott Glacier. The tip of the massif holds Mount Czegka, Acarospora Peak and Dunn Spur. To the north are Mount Russell, Mount Blackburn and Parker Bluff. To the north of Mount Blackburn the Long Valley leads to the head of Griffith Glacier, which is separated from Howe Glacier by Mount Meeks and Skilift Col. Mount Riley and Roaring Ridge are east of Long Valley.

The Watson Escarpment continues east along the rim of the California Plateau past Beacon Dome and Mount Warden. It continues below Maaske Dome and above Evans Butte. To the east of Mount Beazley there is a gap in the escarpment through which the Leverett Glacier flows north towards the Ross Ice Shelf. The escarpment continues east past McLean Peak along the north rim of Stanford Plateau. It passes Phleger Dome and Mount Doumani along the upper reaches of the Kansas Glacier, and passes Foreman Peak and Dzema Peak to the north of Johns Glacier. At its eastern end it passes Cole Peak to its south, and includes Mount Ratliff and Mount O'Neill.

Most of the features along the escarpment were mapped by the United States Geological Survey (USGS) from ground surveys and United States Navy air photos between 1960 and 1964.

Mount Czegka
-86.35°N, -148.68333°W. A mountain, 2,270 m high, on the east side of Scott Glacier, just north of the terminus of Van Reeth Glacier. Discovered in December 1934 by the ByrdAE geological party under Quin Blackburn. Named by Byrd after Victor H. Czegka (1880-1973), CWO, USMC, who served as a member with the ByrdAE, 1928-30, and also as member and supply manager with the ByrdAE, 1933-35.
