Yosemite granite formation.
Over eons rivers and glaciers somehow carved 3 000 feet into solid granite to create yosemite valley.
Yosemite valley as seen from the trail between taft point and sentinel dome.
The bedrock geology of yosemite national park consists almost entirely of granitic rocks.
The glaciers march through the valley was absolutely relentless with the power to shape even gigantic sheets of granite.
About 30 000 years ago a smaller but still relatively massive ice sheet known as the yosemite glacier passed through the valley.
Granite is an intrusive igneous rock which means it crystallized from molten rock called magma miles underground.
The park boundary perfectly frames a landscape that is composed almost entirely of granite and it s no surprise that this landscape contains some of the most iconic rock formations on earth.
