Bainbridge Glacier starts on Pinnacle Mountain, at the edge of the Sargent Icefield on the Kenai Peninsula, and flows east for 10 miles (16 km) to Port Bainbridge, about 36 miles (58 km) east of Seward, Alaska. The glacier name was first reported in 1905 by U.S. Grant, of the U.S. Geological Survey.
Port Bainbridge is a fjord off the east coast of the Kenai Peninsula named in 1794 by Captain George Vancouver, of the Royal Navy, in honor of John Bainbridge who was an astronomer of the 17th century. Bainbridge Glacier, and three smaller glaciers to the north, are on the western shore of Port Bainbridge. The eastern shore is mostly formed by Bainbridge Island and is broken by Bainbridge Passage, Prince of Wales Passage, and Elrington Passage that connect with Prince William Sound.
According to Grant and Higgins, in 1908 this was a tidewater glacier and normal high tides extended to the terminus. They observed fresh push moraines along the glacier’s margin, some with freshly embedded trees and debris indicating a recent advance. A study in 1967 determined that the glacier experienced another advance around 1934 and overrode its 1908 moraine. Today, the Bainbridge Glacier ends well above sea level. The terminus is now on a glacial flat with an ice-marginal lake about 1000 feet (300 m) from the head of a small embayment. A well-vegetated braided outwash plain is located on the southern side of the glacier’s terminus. Read more here and here. Explore more of Bainbridge Glacier here:
