The ridge terminates at the north side of Odom Inlet. Mapped by USGS in 1974. Named by US-ACAN for Jan A.

The peak was photographed from the air by the USAS in December 1940, and was probably seen by the expedition's ground party that explored this coast. First charted by a joint party consisting of members of the RARE and the FIDS in 1947. Named by the FIDS for T.P. O'Sullivan, a member of the FIDS at the Hope Bay base in 1946-47.
