This climber took the leap of faith as she swung off a Yosemite cliff. Professional climber Chelsea Lewis, 23, performed a massive swing while on a climbing trip in Yosemite National Park, California, US. During the annual Yosemite Facelift, where nature lovers from all over volunteer to clean up the parks, Chelsea and Samuel Kizlin climbed up El Capitan, a signature rock formation in the park. With a little assistance and encouragement from Sam, Chelsea used her ropes to swing out from the rock, at a height she estimates to be 200 feet.
