Abstract
Excavations made in connection with the Stillhouse Hollow Dam construction in Bell County, Texas, offered an excellent view of almost complete sections of the floodplain and the two terraces developed in the valley at this point. In the process of work sponsored by the National Park Service, these sections were measured and their lithology recorded. A molluscan fauna was recovered from approximately two tons of sediments quarried from a shallow zone near the base of the T-1 terrace. A radio-carbon date from shells higher in the same terrace indicates an age of 4970 ± 250 B.P., according to the determination of Dr. Meyer Rubin of the U.S. Geological Survey. The tests were run on valves of Tritogonia verrucosa (Barnes), Quadrula pustulosa Lea, and Amblema perplicata (Conrad).
