Mount Rainier National Park, Washington. Bouldery till, exposed in a gully on the north side of Glacier Basin, is part of the old drift. The boulders and smaller stones of various colors in the till are derived from the bedrock that underlies the volcano. The stones are contained in a very hard and compact matrix of brownish-gray silt and sand. Figure 6, U.S. Geological Survey Bulletin 1288. Survey Bulletin-1288
