The Making of Mt. San Jacinto
When the ground shakes the landscape moves up, down or sideways, or a combination of these. How did the granitic rocks of these mountains move up from perhaps 10 miles deep in the earth’s crusts to over 10,000 feet above sea level? What factors together did it and continue the uplift even as weathering and erosion tear them down. (see schedule for Part 2, The Destruction of the San Jacinto Mountains, September 8,) How much higher may San Jacinto peak be resulting from the inevitable “big one” on the southern San Andreas Fault? It could be none, to perhaps, 10 inches or more? I am betting it will be much more than “0”. There is recent precedence for such crustal uplift nearby. Are you ready for that one!? After the slideshow talk, we will check out some of the landforms in plain sight that tell us what has been happening over at least the last 5 million years when the earth shakes. It’s hardly an exaggeration to say it has changed everything. Find out how!
