Spring USA Trip - Day13


We enter the park through the I-40 road on the southwest entrance and stop to explore the Yosemite Valley
From http://www.nps.gov/yose/
“….Yosemite Valley is world famous for its impressive waterfalls, meadows, cliffs, and unusual rock formations….”
Million of years ago, the granite block of Half Dome was larger, but there never was a matching half. Undercut by glaciers near the base, slabs of rock fell away form a broad vertical crack in the granite, leaving a sheer face. Remnants of the missing rock still project from Half Dome’s rim. There are more granite domes at the park than in any other place in the world. Massive granite domes form when large curved layers of rock “exfoliate” or slab off.
Half Dome is perhaps the most recognized symbol of Yosemite. Rising nearly 5,000 feet above the valley floor, it is one of the most sought-after landmarks in Yosemite.
Then we drive to the southern part of the park to visit the Mariposa Grove of Giant Sequoias. “….The Mariposa Grove is located 36 miles (one hour) south of Yosemite Valley, near the park's South Entrance. The Mariposa Grove is the largest stand of giant sequoias (also known as Sierra redwoods or big trees) in Yosemite….”
