THE ANSEL ADAMS WILDERNESS spans an area of 231,533 acres. Elevations within the wilderness range from 3,500 ft at Hells Half Acre along the Middle Fork San Joaquin River, to 13,157ft at the summit of Mt. Ritter. It is arguably some of the most beautiful landscape to be found anywhere in the world.The wilderness was renamed from the Minarets Wilderness to honour the famous landscape photographer and environmentalist by the 1984 California Wilderness Act. The 1984 law also more than doubled the size of the Minarets Wilderness, extending it south from its original southern boundary in the vicinity of Hemlock Crossing and Devils Postpile all the way to its current extent near Lake Thomas Edison.
Mt. Ritter and Banner Peak along with the Minarets are awe inspiring for climbers and outdoors men of all types. John Muir considered the alpine beauty in this area to be unsurpassed by any other terrain in all the range. He also considered Ediza Lake to be the most beautiful of all the multitudes of lakes in the Sierra.

Psalm 8:3-9When I consider your heavens, the work of your fingers, the moon and the stars, which you have set in place, what is man that you are mindful of him, the son of man that you care for him? You made him a little lower than the heavenly beings and crowned him with glory and honor. You made him ruler over the works of your hands; you put everything under his feet: all flocks and herds, and the beasts of the field, the birds of the air, and the fish of the sea, all that swim the paths of the seas. O LORD, our Lord, how majestic is your name in all the earth!
