BOULDER RIDGE GOLF COURSE IN SOUTH SAN JOSE: Do these boulders found along the ridge of a mountain leading to Boulder Ridge Golf Course show a high energy outcropping of highly eroded rocks which at one point likely were either submerged in water and/or at water's edge; likely back when the Central Valley in California was the largest body of freshwater in the world after the last ice age?

High energy outcroppings @ Boulder Ridge Golf Course
A simple explanation of this suggests that while large quantities of ice caused glaciation in the Sierra Nevada mountain range; heavy snow pack remained on the Santa Cruz mountains as well until the end of the last ice age (one of several ice ages) when this snowpack finally melted and formed a huge ancient freshwater lake (X = Boulder Ridge Golf Course). Note: This fresh water lake was mainly fed by the Pajaro River.

But a more complex explanation could be within this (see photo below): It is widely accepted that the Central Valley region (D) was at one point in history the largest body of fresh water on earth (note: the Sacramento region [D] lies below sea level). Fed by glacial runoff from the Sierra Nevada mountain range; most of the runoff initially exited through the Monterey Bay region and/or Soquel Canyon (A); until a large earthquake occurred at the Carquinez Straits (C); allowing water from the Central Valley region to spill into what is now the San Francisco Bay region; flooding the entire region and ultimately exiting through the Golden Gate.
Another theory is based upon ancient Native American legends suggesting there was once a Golden Gate land bridge (B) that broke open when a large earthquake occurred along the San Andreas fault. In this theoretical scenario; the entire San Francisco Bay region was part of that initial body of Central Valley fresh water; when activity on the fault broke open the land bridge and created the Golden Gate (B). Adding to this; inhabitants who supposedly lived on dry land outside of what is now the Golden Gate (B) were then allegedly submerged under water!?
Another possible scenario mixes together both theories: the large earthquake mentioned in Native American legend perhaps actually happened at the Carquinez straits; allowing water to flow into what is now the San Francisco Bay region; eventually eroding and breaking open what would later become known as the Golden Gate.
