A turret-like rock knob 1,990 metres (6,530 ft) high standing 1.5 nautical miles (2.8 km; 1.7 mi) northwest of Fairchild Peak, just south of the mouth of Tillite Glacier.

So named by the Ohio State University geology party (1966-67) because the only safe route to Tillite Glacier lies between this rock and Fairchild Peak.

The name was suggested by John Gunner of the Ohio State University Geological Expedition, 1969-70, who was landed by helicopter to collect a rock sample here.

Named by US-ACAN for Major William C. Hampton, commanding officer of the United States Army Aviation Detachment which supported the Texas Tech-Shackleton Glacier Expedition, 1964-65.

So named by the Ohio State University Geological Party, 1967–68, because an excellent exposure of.the Kukri Peneplain, an ancient erosion surface, is present on the peak.
