Nevertheless, the springs and seeps in the park are necessary to the survival.

Cellular signals are weak to non-existent and should not be depended on while visiting the park.

blue cut fault joshua tree Dec 20, Joshua Tree is crisscrossed with hundreds of faults, and it is a great place to see raw rocks and the effects of earthquakes. The famous San Andreas Fault bounds the south side of the park and can be observed from Keys View. Blue Cut Fault in the center of the park can be seen from the hilltop behind Lost Horse Mine. Apr 09, The Blue Cut made a lot of sense (if you are into what they call “scud running”). The crest of the Blue Cut forms sort of a pass between Joshua Tree NP and the lower desert to the south.

Someone familiar with the area’s terrain might be tempted Estimated Reading Time: 7 mins. The Blue Cut fault bisects Joshua Tree National Park (JTNP), from the Little San Bernardino Mountains to the west through the Pinto Basin to the east. It is part of a series of active sinistral ENE-trending faults that originate along the southern San Andreas fault; these include, from S to N, the Salton Creek, Chiriaco, Blue Cut, and Pinto Mountain faults (and perhaps the Garlock fault, further north).

Sep 15, The Blue Cute cat tree fault is named for the granodiorite (a combination of granite and diorite minerals) that has a"bluish" tinged color possibly caused by stressed quartz or stressed feldspar that occurred along the fault zone.

The Blue Cut fault scarp and its associated bluish granodiorite is exposed on the mountainside directly to the west and across Pleasant Valley. Joshua Tree is crisscrossed with hundreds of faults, and is a great place to see raw rocks and the effects of earthquakes.

It was the upward pumping of monzogranite -- a particular form of molten rock -- that eventually gave birth to the landscape that now greets us.

The famous San Andreas Fault bounds the south side of the park, and can be observed from Keys View. Blue Cut Fault in the center of the park can be seen from the hilltop behind Lost Horse Mine.

The fault forms the straight, abrupt base of the Hexie Mountains east of Queen Valley. Geologic fault zones are key to Joshua Tree, for they bring life-saving water to the surface in the form of springs. These springs, in turn, create oases that nourish vegetation and wildlife. The Pinto Mountain Fault wraps the northwestern lobe of the park, the San Andreas Fault undercuts the southern boundary, and the Blue Cut Fault traverses.
