is a snow-covered col, 185 m high, between Red Rock Ridge
and the Blackwall Mountains
, on the west coast of Graham Land
. First surveyed in 1936 by the British Graham Land Expedition
(BGLE) under Rymill. Resurveyed in 1948-49 by the Falkland Islands Dependencies Survey
(FIDS), and so named by them because the col affords a safe sledging route between Neny Fjord
and Rymill Bay
when there is open water off the west end of Red Rock Ridge.
