Chazy Reef

The Chazy Group consists of the Day Point, Crown Point, and Valcour formations and is exposed in areas along the northwestern edge of Lake Champlain and in a few islands within the lake itself.  The Crown Point and Valcour formations contain abundant trilobites, which were documented by Shaw in 1968.  I plan to study the ecologic relationships of the trilobites to the reefs that are preserved in the Valcour Formation and conduct some long-overdue revision of the phylogenies of some of the groups of trilobites.
