The Pomerantz Tableland (70°38′S 159°50′E / 70.633°S 159.833°E / -70.633; 159.833) is a 2,290 metres (7,510 ft) high ice-covered tableland about 10 miles (16 km) long, standing 15 miles (24 km) northwest of Daniels Range.[1]

Early exploration and naming

The Pomerantz Tableland was mapped by USGS from surveys and U.S. Navy air photos in 1960–62. Named by US-ACAN for Martin A. Pomerantz, Director of the Barthol Research Foundation and Chairman of the U.S. Committee for the International Year of the Quiet Sun, who carried on cosmic ray studies in the McMurdo Sound area, 1959–60 and 1960-61.[1]

A glacier about 8 miles (13 km) long which drains the east slopes of Pomerantz Tableland southward of Armstrong Platform, in the Usarp Mountains. Mapped by USGS from surveys and U.S. Navy air photos, 1960-62. Named by US-ACAN for Merritt R. Helfferich, USARP worker in the field of ionospheric physics at South Pole Station, 1967-68.[2]
