Yosemite National Park is a national park in eastern central California known for its grand waterfalls, impressive granite cliffs, towering sequoias, and vast wilderness. The bulk of visitors to Yosemite converge on Yosemite Valley, an 18 km2 glacier-carved valley where most of the park facilities and natural landmarks are located. On our visit to Yosemite last February 2013, we stopped at Tunnel View, a viewpoint at the end of Wawona Tunnel, where three of Yosemite’s prominent landmarks can be seen in one frame: El Capitan granite cliff on the left, Bridalveil Falls on the right, and Half Dome straight ahead in the center.
