Abstract
Over 1000 vertical feet of loose to weakly consolidated Tertiary and Quaternary sediments occupy the closed Lemmon Valley basin. Mountains comprising Mesozoic granitic and metavolcanic rocks border the valley. Fourteen Quaternary geologic units within the forty-eight-square-mile field area include pediment gravels, six varieties of alluvium, beach, forebeach, lake, landslide and playa deposits, windblown sand and playa-bordering clay dunes. North-south and northeast-southwest trending normal faults cut early Pleistocene deposits and delineate subordinate horsts and grabens within the basin. The prominent Airport fault offsets Tertiary and early Quaternary sediments 120 feet and granitic bedrock over 600 feet vertically. Hazards to valley inhabitants include flooding, faulting, seismic shaking, landsliding, and expansive soils. Losses of construction aggregate resources and overdrafting of domestic ground water supplies may occur through over-population of the valley as demands for more housing are made by the neighboring Reno-Sparks community.
