Guyot Glacier, Icy Bay

Guyot Glacier, Icy Bay

by | Aug 14, 2020

Guyot Glacier is 34 miles (55 km) long and 8 miles (13 km) wide and located in the Robinson Mountains, about 146 miles (235 km) east-southeast of Cordova and 76 miles (123 km) northwest of Yakutat, Alaska. The glacier begins 5.6 miles (9.0 km) north of Yaga Peak and flows east-southeast to the head of Icy Bay, with the terminus just south of the Guyot Hills. The glacier was named by the New York Times Expedition of 1886 for Arnold Henry Guyot, of Princeton University, and applied to what was then considered the west lobe of the Malaspina Glacier.

Arnold Guyot was a Swiss-American who became a professor of physical geography and geology at Princeton University. He was the first to point out important observations relating to glacial motion and structure, such as the more rapid flow of the center than of the sides, and the more rapid flow of ice at the top than of the bottom of glaciers. His scientific work in the United States included plans for a national system of meteorological observations.

Icy Bay is a large embayment in Southeast Alaska that formed in the last 100 years by the rapid retreat of the Guyot, Yahtse, and Tyndall Glaciers. At the beginning of the 20th century, the bay entrance was permanently blocked by a giant tidewater glacier with a terminus that calved icebergs directly into the Gulf of Alaska. Glacial retreat has since opened a multi-armed bay more than 30 miles (48 km) long that is now part of the Wrangell-Saint Elias Wilderness. Read more here and here.

About the background graphic

This ‘warming stripe’ graphic is a visual representation of the change in global temperature from 1850 (top) to 2021 (bottom). Each stripe represents the average global temperature for one year. The average temperature from 1971-2000 is set as the boundary between blue and red. The color scale goes from -0.7°C to +0.7°C. The data are from the UK Met Office HadCRUT4.6 dataset.
