Zinsmeister Ridge is the high, rugged mountain ridge, 9 mi long, running northeast from Schoening Peak, Vinson Massif in the Sentinel Range, Antarctica. Jagged 2000 to 3000 m peaks including Vanand and Toros Peaks surmount the ridge, which separates Hinkley Glacier from the upper part of Dater Glacier. The ridge is named by US-ACAN (2006) after William J. Zinsmeister, Department of Earth and Atmospheric Sciences, Purdue University, USAP researcher of the paleontology (molluscan fauna) of Seymour Island, 1975–95. Maps Vinson Massif.
