Abstract
Observations of the molluscan population of five ponds were conducted during the summer of 1960. Four of the ponds, Colter Bay, Jackson Dam, Pacific Creek No. 1 and 2 lie in the lodgepole forest. The fifth, Gros Ventre, is out on the plain along the Gros Ventre River. They are closed drainage basins, filled to a depth of a few feet by the spring runoff and underground seepage. Project Number 72.
