Tillite Spur

Tillite Spur (85°59′S 126°36′W) is a narrow, steep-cliffed rock spur that is about 5 km (3.1 mi) long. It descendes from southern Wisconsin Plateau between Red Spur and Polygon Spur and ends at the east side of Olentangy Glacier. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1960–64. The name was proposed by John H. Mercer, United States Antarctic Research Program (USARP) geologist to this area in 1964–65, because tillite forms the crest the spur for its entire length. The tillite crest overlies steep, bedrock cliffs.[1][2]
