Excerpt from Fossil Mammalia of the White River Beds of Montana, And, the Tertiary of Montana Most of the material in the beds that are undoubtedly White River is light colored, fine grained. And soft, though there are some layers of coarser and harder material. The same is true of the beds that, from their lithological characters and imperfect fossils, have been supposed to belong to the same horizon. The nearness or distance of the shore or the mountains and the character of the contiguous rocks seem to have little in uence on the character or composition of the sediments.
