General and Engineering Geology of the Wray Area, Colorado and Nebraska

From abstract: Most of the formations in the Wray area are fair foundation materials, although good construction materials are scarce. The gravel of the Grand Island formation and the gravels in the Ogallala formation contain large quantities of clay, silt, sand, and calcium carbonate, and have very few pebbles larger than one-half inch in diameter.
