FORMATION OF A MODERN ICE-PUSH RIDGE BY THERMAL EXPANSION OF LAKE ICE IN SOUTHEASTERN CONNECTICUT.
A modern ice-push ridge on the northwest shore of Gardner Lake in southeastern Connecticut is 0.6-1.2 m high and 1.2-3.1 m wide. In February and March 1967, the positions of survey stakes placed on the lake ice were measured periodically. During the same period, air and ice temperature and solar rad...
