A type of fault activity called block faulting , in which the movement is predominantly vertical, began to form the valley about 30 million years ago. Portions of the great For a short time after its christening in 1849 by a hapless party of emigrants who endured intense suffering while crossing it, Death Valley was little known except to Native Americans (primarily The geologic history of Death Valley is extremely complex and involves different types of The floor of Death Valley is noted for its extremes of temperature and aridity. Located in Antelope Valley, Palmdale sits right on top of San Andreas Fault Line.
Most of the salt is haltite, although other evaportie minerals are present along the edges. Most earthquakes that occur today are very small and cause no damage to structures or the ground surface.
The Death Valley fault line is primarily a normal fault (Brogan, 1991).
However, at some point in the future (no one knows how long into the future), the major fault systems in Death Valley are almost sure to create a significant seismic event. Badwater Spring issues from a recently active fault along the front of the Black Mountains, visible as two fault scarps in the background on the alluvial fan (G-04) Wineglass Canyon and fault.
Wineglass Canyons also indicate recent uplift because uplift at the canyon mouth keeps pace with erosion and maintains a steep gradient. Death Valley is located in the southwestern portion of the Basin and Range geomorphic province. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree....

The Basin and Range province has a long and active geologic history, including faulting and regional tectonic movement. Normal faults mean that the hanging wall moves downward in relation to the footwall and are usually indicators of tensile forces. Fault-bounded uplifted ranges are separated by down-dropped sedimentary basins.Most faulting that is presently occurring within Death Valley is strike-slip (transverse) with a component of normal movement (see Figure 1).
Along normal faults rocks above the fault move down relative to those below the fault. Two types of faults are common in Southern Nevada: normal and strike slip.
