Tilted sedimentary rock layers at Vasquez Rocks in Southern California formed 25 million years ago and have been shaped by tectonic activity along the San Andreas Fault
The Vasquez Rocks in Southern California are characterized by sedimentary rock layers tilted at an average angle of 50 degrees. These rocks formed about 25 million years ago from alluvial fan deposits that later became sandstone and conglomerate. Tectonic forces related to the San Andreas Fault caused uplift, folding, and tilting of these sedimentary layers. Ongoing weathering and erosion further sculpted the formations visible today. The site is known as a popular filming location, notably for the Star Trek franchise. These facts are supported by imagery and analysis from Landsat 9 and NASA Earth Observatory as of July 28, 2026 (sourceId: "nasa-news-releases").
