The Watchman is a massive flow of andesite two-fifths of a mile wide and extending one and one-quarter miles downhill. It supports an impressive dike on the lake side.The Watchman flow has a distinct topographic expression. Its length is almost 1 1/4 miles and its average width 2000 feet. The average thickness is between 400 and 500 feet. The flow must have been unusually viscous, for the snout and sides are extremely steep. Of particular interest is the attitude of the flow planes ….
