The 600 m long horseshoe-shaped flat saddle of elevation 420 m lies between Rezen Knoll and Burdick Ridge in eastern Livingston Island, affording overland access from Balkan Snowfield to upper Perunika Glacier and Bowles Ridge area. First visited by the Bulgarians Kuzman Tuhchiev, Dimo Dimov and Ivan Tashukov from St. Kliment Ohridski Base during the 1994/95 season. The feature takes its name from the adjacent Rezen Knoll.
