"The Power of Nature" - Yosemite Valley's 1997 Flood Video
A look back to Yosemite Valley during the historic January 1997 flood. Video compliments of the National Park Service. 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—most recently in January 1997. See what the Valley looked like during floods in May 1996 and January 1997.
