Floods in Yosemite Valley aren't uncommon during spring, when the Merced River swells with melted snow. The largest, least common floods occur during winter. See what the Valley looked like during the large floods in May 1996 and January 1997.
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.
