Yosemite Valley, the most remarkable gorge in the world, in the centre of California, 140 m. E. of San Francisco, 6 m. long and from ½ to 24 m. broad, girt by perpendicular walls thousands of feet deep and traversed by the river Merced in a succession of falls of great height, the whole presenting a scene of mingled grandeur and beauty; it was discovered in 1851, and steps are being taken by Congress to preserve it as a place of public resort and recreation.
