How did Kings Canyon form?

Kings Canyon was formed primarily through the process of glacial action. As part of the Sierra Nevada, the region's dramatic topography is the result of the range's history as an upfaulted, tilted block of the Earth's crust.12

While the broader Sierra Nevada range was uplifted and tilted westward—creating steep-gradient canyons through the erosive forces of wind, rain, frost, and ice—the specific, spectacular features of Kings Canyon were carved by the movement of glaciers. This process resulted in massive granite walls that rise up to 4,000 feet above the canyon floor within the park, with depths reaching as much as 8,200 feet in areas outside the park boundaries.21
