The oldest rocks in California date back 1.8 billion years to the Proterozoic and are found in the San Gabriel Mountains, San Bernardino Mountains, and Mojave Desert.The rocks of eastern California formed a shallow continental shelf, with massive deposition of limestone during the Paleozoic, and sediments from this time are common in the Sierra Nevada, Klamath Mountains and eastern Transverse ...
The Mojave River is an intermittent river in the eastern San Bernardino Mountains and the Mojave Desert in San Bernardino County, California, United States. Most of its flow is underground, while its surface channels remain dry most of the time, except for the headwaters and several bedrock gorges in the lower reaches.
Contrary to popular belief, the tar pits don't contain dinosaur remains, as these were extinct before the pits formed. [27] The park is known for producing myriad mammal fossils dating from the Wisconsin glaciation.

A submerged forest is the in situ remains of trees, especially tree stumps, that lie submerged beneath a bay, sea, ocean, lake, or other body of water. These remains have usually been buried in mud, peat, or sand for several thousand years before being uncovered by sea level change and erosion and have been preserved in the compacted sediment ...
The remains contain the head and the anterior part of the body preserved to the edge of the chest. The mummy's head was especially well-preserved, and the forelimbs of the mummy were preserved ...
