FORMATION OF LAKE ICE IN A TEMPERATE CLIMATE
The formation of lake ice in a temperate continental climate was studied during the winter of 1956-1957 at Post Pond, Lyme, New Hampshire. In the thirty-six blocks of ice studied, four textures and three structures were observed. The textures, tabular, columnar, granular, and crenulate, are discusse...
