Abstract: Information on sea ice conditions in the Bering Strait and the icefoot formation around Fairway Rock,located in the strait, is presented. Cross-sectional profiles of Fairway Rock and the relief of the icefoot are given along with theoretical analyses of the possible forces active during icefoot formation. It is shown that the ice cover most likely fails in flexure as opposed to crushing or buckling, as the former requires less force. Field observations reveal that the Fairway Rock icefoot is massive, with ridges up to 15 m high, a seaward face only 20° from vertical, and interior ridge slopes averaging 33°. The icefoot is believed to be grounded and its width ranges from less than 10 to over 100m.
