MUIR GLACIER, an Alaskan glacier discovered in 1878 by John Muir. The ice forming it flows down the slope of Mount Fairweather, over 15,000 feet high, and enters Glacier Bay, forming a wall of ice nearly two miles long and from 135 to 200 feet high. From the lower end break off great icebergs which are carried away to sea.
