The 2013 Rim Fire was the largest forest fire in California history, and the largest fire in Yosemite history. Burning 400 square miles, the speed and size of the fire was unprecedented. As these unnaturally large fires become more commonplace due to previous fire suppression and climate change, Yosemite National Park is seeing the benefits of carefully allowing smaller, controlled fires on the landscape.

In the spring of 2006, a rockslide buried a section of Highway 140 just outside of Yosemite National Park. The slide remained highly active for many days, allowing rare views of a rockslide in motion. The rockslide has been bypassed with temporary bridges, allowing Highway 140 to remain open. This footage was shot after the main rockslide, but while movement was still occurring.
