Yosemite National Park: Water is the life-blood of Yosemite National Park. The Tuolumne and Merced rivers water some of the most productive farmland on the Earth, and urban dwellers throughout the state depend on the Sierra Nevada snowpack for their domestic water needs.

Yosemite National Park: Throughout the Sierra Nevada, high flat plateaus are found at elevations around twelve and thirteen thousand feet. These isolated sky islands are the home to unique plant communities that are found nowhere else.

Yosemite National Park: Horsetail Fall is a small, ephemeral waterfall that flows over the eastern edge of El Capitan in Yosemite Valley. For two weeks in February, the setting sun striking the waterfall creates a deep orange glow that resembles Yosemite's historic, "Firefall."
