33 ROCHESTER ACADEMY OF SCIENCE. [Jan. 27, 
The topic being the action of ice, Mr. Howell spoke of the possible 
causes of the glacial area being mostly east of the Rocky mountains. 
He also described a peculiar ridge around Fish lake, Utah. This was 
a glacial lake, gooo feet above sea level and held by a glacial moraine. 
The ridge was formed by the expansion and contraction of the ice 
under changes of temperature ; in expansion the ice pushed up the 
loose material until a “windrow” three to four feet high had been 
accumulated.
