REMARKS: The valley boeeom remains cold through much of the summer months. Narrow valley walls channel and trap winter air currents so that the valley bottom remains cool thoughout the year. The wildflower snow trillium (Trillium nivale) is found here as well as other plants normally found in more northern climates. Rocks exposed in the valley walls are sandstones, siltstones, and shales of the Glenshaw Formation of the Conemaugh Group (Pennsylvanian age).
