Upper and Lower Yosemite Falls. At 2,425 feet, Yosemite Falls is the tallest waterfall in North America, and fifth highest in the world. Upper Yosemite falls is 1,430 feet, then there's a middle cascade of 675 feet that's not visible in this picture (you can see it later in my Sentinel Dome shots though). Finally, the Lower Yosemite falls is 320 feet tall.

A bit of trivia for you: the Yosemite Falls Trail is one of the oldest in the park, having been established in 1870. If you want to hike it, be prepared for a bit of a walk -- it's a 7.2 mile round trip with an elevation gain of 2,700 feet.

Yosemite Creek. The mist at the top of this picture is actually created by the force of the lower fall hitting the rocks.
