Geological Features of Yosemite Valley

The video explains the geological history of Yosemite Valley, starting with ancient rock layers and the subduction of the Farallon Plate under the North American Plate. This process led to the formation of a massive magma plume that solidified into granite. Over time, erosion and glaciers sculpted the Sierra Nevada mountains, creating the stunning landscapes we see today. The video concludes with an invitation to visit California and witness these natural wonders.
