Gravelly stream alluvium
Pleistocene, younger than 781,000 years. 1 crag on this site has its map point on it.
What the map says
Small deposits of poorly sorted and poorly to well stratified stream gravel and probably finer-grained sediment in valleys, west of the Dakota hogback, in the eastern part of the map area. Clasts are commonly of Precambrian rock, but locally are derived from nearby sedimentary rocks; many of the clasts are weathered. Calcium carbonate cement is locally abundant (Braddock, Wohlford, and Connor, 1988; Courtwright and Braddock, 1989). Deposits near Table Mountain are about 18 m and locally 24 m above Boxelder Creek and about 12 m above some of its tributary streams. Deposits west of Livermore, Colo., are about 24 m and 37 m above the North Fork Cache la Poudre River and about 24, 37, 60, and 85 m above some of its tributary streams. Unit locally includes fan deposits (Qf) and pediment deposits (Qp). Deposits of unit Qg are a potential source of fill and road subbase material. Estimated thickness is 3–15 m Lithology: gravel, sand.
