Walker Lane

  Close-up of
 Walker Lane region, between Sierra Nevada Mountains and the Basin and RangeWalker Lane is a linear north-northwest trending depression extending some 800 km (500 miles) north from the Garlock Fault-Las Vegas area to south-central Oregon. Within it are Walker, Goose, and Pyramid Lakes. This trough is part of the Walker Lane Fault Zone, a major tectonic system that includes Owens and Death Valleys and several prominent faults, and is the site of many contemporary earthquakes. Located at the juncture of two contrasting tectonic styles, the Sierra Nevada and the Basin and Range, the Walker Lane region is deforming in a complex way by both extensional and transcurrent (sliding) fault movements.
