General: This very long, nearly continuous fault zone has: (1) range-front faults bounding east front of Pine Nut Mountains from south end of range to east of Boyle Tunnel and bounding east front of Buckskin Range, Wellington Hills and Sweetwater Mountains; (2) piedmont and intrabasin faults throughout much of Sweetwater Flat, in western and southern Smith Valley, in northwest arm of Smith Valley, and on east piedmont slope of Buckskin Range; and (3) a few intermontane faults east of Desert Creek Peak and in volcanic plateau flanking east side of Pine Nut Mountains near Lyon Peak. Pine Nut Mountains and Wellington Hills represent a west-tilted structural block and Smith Valley probably is a west-tilted half graben based on presence of a marsh on west side of valley near Beaman Lake. Generally, zone is expressed as scarps on Holocene, upper Pleistocene, and older Pleistocene alluvium and juxtaposes Holocene and upper Pleistocene alluvium. Range-front faults juxtapose piedmont-slope deposits against bedrock and are expressed as locally abrupt fronts of Pine Nut Mountains, Wellington Hills, and Sweetwater Mountains. Piedmont faults are marked by a small group of scarps at south end of Smith Valley, adjacent to front of Pine Nut Mountains, Sweetwater Mountains, and Buckskin Range. Some of intrabasin faults in southern Smith Valley and in Sweetwater Flat are characterized by short scarps. Intermontane faults east of Desert Creek Peak are delimited by aligned drainage valleys and ridge-crest saddles, and near Lyon Peak are marked by prominent escarpments, two of which bound a large closed depression that appears to be a graben. Although many of these faults displace only bedrock, some also displace Pleistocene alluvium or juxtapose younger against older Pleistocene alluvium, providing evidence for young movement. Detailed work has not been conducted along entire fault zone; reconnaissance photogeologic and field-based mapping of fault zone are the sources of data. Trench investigations have not been completed, but characterization of the scarp morphology has been accomplished for parts of fault zone in Smith Valley and Sweetwater Flat.

thats up near reno im talking southern nevada. might want to look at USGS to see what im talking about.
right state wrong area my friend.edit on 18-2-2012 by omegacorps because: (no reason given)
