The image above displays El Capitan, located in Yosemite National Park. El Capitan is the largest monolith of granite in the world. The collision of tectonic plates caused its formation some 220 million years ago. There are a number of different types of granite rocks on the face of El Cap, however they were all formed from the heating of the magna under the surface from the collision of the plates. Glaciers then carved through and created the valley floor 3 million years ago, putting the final touches on the mountain. This is an absolutely astonishing geological formation and attracts many experienced rock climbers every year.
