I’ve been asked about the source for the quartzite clasts in Puget Lowland glacial till. They are diagnostic of a British Columbian provenance for the Puget Lobe of the Vashon advance, and the great glaciations that preceeded that one. Go to the quartzite page, where I discuss the source for these pebbles, and attempt to confuse everyone because there are two kinds of quartzite.
