The Muddy Creek formation underlies the Qa. The Muddy Creek formation underlies much of the Las Vegas Valley and is more than 2,000 feet thick in places. The upper portion beneath the site is referred to as TMCf. The soil of the TMCf underlying the site is typically fine-grained (sandy silt and clay silt), although layers with increased sand content are also sporadically encountered.
