He traveled and worked in Antarctica on two occasions, 1973 and 1975.

Mount Lopatin
-72.85°N, 168.06667°W. A mountain 2,670 m high situated 6 nmi east-southeast of Mount Riddolls. Mapped by USGS from surveys and United States Navy air photos, 1960-64. Named by US-ACAN for Boris Lopatin, Soviet exchange scientist at McMurdo Station, 1968.

Mount Frosch
-72.76667°N, 167.91667°W. A mainly snow-covered mountain 2,750 m high standing 3 nmi northeast of Mount Riddolls at the head of Borchgrevink Glacier. Mapped by the USGS from surveys and United States Navy aerial photographs, 1960-62. Named by US-ACAN for Robert A. Frosch, Assistant Secretary of the Navy for Research and Development, 1971-72; Administrator, National Aeronautics and Space Administration 1978.

Hackerman Ridge
-72.65°N, 167.76667°W. A large mountainous ridge trending north–south between the Gruendler and Rudolph Glaciers. Named by US-ACAN for Norman Hackerman, member of National Science Board, 1968-78; Chairman since 1974. He visited Antarctica in 1975 and 1977 as part of his official duties in support of the United States scientific program in Antarctica.

Mount Randall
-72.8°N, 167.66667°W. A mountain rising to 3,000 m high at the south end of Hackerman Ridge. The mountain, which forms the summit area in this part of the ridge, is 2 nmi west of Mount Riddolls and 3.5 nmi northeast of Mount Burrill, with which this name is associated. Named by the US-ACAN in 1994 after Richard R. Randall, geographer and cartographer, Executive Secretary, United States Board on Geographic Names, 1973-93, whose office included responsibility for geographic nomenclature in Antarctica. Succeeding Meredith F. Burrill as Executive Secretary, Randall combined with Burrill to direct a half-century of American geographic names research.
