Mapping and name

The Grossman Nunataks were mapped by the United States Geological Survey (USGS) from surveys and United States Navy aerial photographs, 1961–68, and from United States Landsat imagery, 1973–74. They were named by the United States Advisory Committee on Antarctic Names (US-ACAN) in 1994 after Charles Grossman, formerly Chief of the Shaded Relief and Special Graphics Unit, Branch of Special Maps, USGS, a specialist in the production of maps of Antarctica.[1]
