||Unsorted to poorly sorted, clay, silt, sand, gravel and diamicton deposited by glacial ice. Abundant erratics are polyhedral, striated, and subrounded, relatively fresh granitic boulders up to 6.5 feet (2.0 m) in diameter derived from 1) the Revelation Batholith; 2) Tired Pup, two-mica Pluton (southern edge of Revelation Mountains, and 3) hornblende rich tonalite which are collectively granitic types making up the core of the Alaska Aleutian Range Batholith. Prominent moraines are not dissected by small second and third order streams, but cut by the Swift, Stony, and Big Rivers. Irregular craggy Moraines contain from 7-15 kettles per km2. In Big River, the terminal ice position is marked by a prominent granitic boulder field in a restricted 4-mile-long canyon, about 8 miles (12 km) below the confluence of Lyman Fork and Big River. Distinctive lateral moraines ranging from 1,600 to 2,400 feet (490670 m) in elevation mark Qmw-4 moraines in the valleys of Stony, Swift, and Big Rivers as they break out onto the piedmont west of the mountain front. A large pro-glacial lake deposit (Qgl), is damned up behind Qmw-4 moraines in the valley of Stony River; the 1214 mile long (19-22 km), ancestral lake is centered on the mouth of the Telequana River where it enters Stoney River. Bundtzen and others (1994) show Qmw-4 deposits in Lime Hills C-5 quadrangle as Qgt-2 deposits of Late Wisconsin age. Qmw-4 deposits are probably equivalent to either the Newhalen or Iliuk stades of the Brooks Lake Glaciation as defined by Detterman (1986). Qmw-4 is also equivalent to the terminal ice position that damned up glacial Lake Telequana in Lake Clark Quadrangle (unit Qw3 of Wilson, 2004, unpublished)
