Students used Brunton compasses to measure the angles of repose in fresh sand and gravel talus exposed in artificial pits in a kame terrace near Willimantic, Connecticut. The angle of repose was found to average 33.08°, and is independent of exposure direction or material type. Measurements also were made on natural forested hillslopes of the same sand and gravel along a terrace scarp where the Nachaug River had cut into it. The hillslope averages 41.29° and is independent of exposure direction. The difference between the angle of repose and the natural hillslope is attributed to the stabilizing influence of the forest vegetation.
