Nature
Muir Glacier, a valley glacier in Glacier Bay National Park and Preserve in southeastern Alaska, is tied both to John Muir’s visits in 1879 and 1880, which helped focus attention on Glacier Bay and its protection, and to one of Alaska’s clearest records of rapid modern glacial retreat. Ice once filled much of Glacier Bay, and Muir Glacier was long a prominent tidewater glacier connected to Riggs Glacier. Over the 20th century it withdrew and thinned dramatically, while ocean water flooded the valley to form Muir Inlet. Closely observed for more than a century, it has become a landmark of Glacier Bay’s changing landscape.
