Determine the amount of throw across the two faults labeled AA and BB, located near the southern edge of the map. Because the Tertiary and Cretaceous strata are not dipping, you may use the elevation of units on either side of the fault to estimate throw. The contour interval is 50 feet. Convert your answers to meters and use significant digits. joes Valley Reservoir, located in the northern part of the map, occupies a sedimentary basin partially filled with Quaternary alluvium. What is the structure that creates this basin (hint: the answer does not have the word 'fault' in it.) The wider zone of faulting at Ferron Canyon, located in the southern part of the map, is an example of what kind of structure?

Unconsolidated. Consists of clay, silt, sand, granules, pebbles, and sparse cobbles. Fluvial sediments. Forms broad, even surfaces of low relief. Locally includes higher patches of "older alluvium". Thickness ranges widelu: commonly less than 15 m (50 ft) thick COLLUVIUM (HOLOCENE)-Brown to dark-brown heterogeneous mixture of fragments of many sizes and shapes which locally mantles lower valley walls and accumulates at the base of some steep cliffs. Unconsolidated to semi- consolidated debris. Thickness ranges from a few centimeters (one inch) to as much as 15 m (50 ft) ALLUVIAL FAN DEPOSITS (HOLOCENE)-Light brown to brown, locally gray, unconsolidated to semiconsolidated; moderately well sorted silt, sand, granules, pebbles, or cobbles at the mouths of streams. Fluvial sediments. Commonly lobate. Thickness uncertain, probably as much as 15 m (50 ft) locally EARTHFLOW DEPOSITS (HOLOCENE AND PLEISTOCENE)-Brown to dark brown; sand, granules, pebbles, cobbles, and boulders in an unsorted matrix of clay and silt. Unconsolidated to semiconsolidated debris. Masses of detritus that have flowed downslope to form elongate, hummocky, lobate land forms. Thickness varies widely; probably as much as 45 m (150f) thick locally MASS-WASTING DEPOSITS (HOLOCENE AND PLEISTOCENE)-Brown to dark brown heterogeneous masses of mixed country rock, of diverse sizes and shapes that have slid downslope repeatedly as both small slumps and large debris flows.
