The Late Cretaceous to Paleocene(?) Canaan Peak Formation of southwestern Utah is comprised of approximately 100 m of cobble conglomerate and subordinate sandstone. Gravel deposition occurred during high-discharge periods within a Scott-type, perennial, braided fluvial system as longitudinal (Gm) and sinuous-crested transverse (Gt) bars, and as a product of longitudinal bar-top and inter-bar channel scour filling (Gt). Sand accumulated under lower flow velocity conditions through migration of inter-bar channel dunes and transverse bars (St/Sp) and development of scour-and-fill deposits (Ss). Siltstone (Fm) deposition resulted from vertical accretion on bar tops during waning flow conditions; Clast imbrication and trough axis orientation measurements indicate east to northeast paleoflow directions; Canaan Peak Formation detritus was derived from erosion of highlands created by Cretaceous Servier-style thrust faulting to the west in southeastern Nevada and western Utah and was distributed across an extensive gravel-dominated braid-plain complex. Sediments represent multiple-cycle deposits that were transported eastward a minimum distance of 70 to 80 km. (Abstract shortened with permission of author.).
