Half Dome is a granite dome at the eastern end of Yosemite Valley in Yosemite National Park, California. It is a well-known rock formation in the park, named for its distinct shape. One side is a sheer face while the other three sides are smooth and round, making it appear like a dome cut in half. The granite crest rises more than 4,737 ft above the valley floor. George G. Anderson was the first to scale its walls in 1875. You can also hike to the top using the 8.5 mile Cable Route trail. Explore it all with this 24"x 30" 1000 piece puzzle. By O W Lawrence
