It extends 2.2 km in an east-southeast to west-northwest direction between Ogosta Point on the Rozhen Peninsula and the opposite coast of Hurd Peninsula at a depth of over 50 m, with depths exceeding 100 m on both sides of the ridge. It was formed as a frontal moraine of Huntress Glacier between the 13th and 17th centuries.
