Tyndall Glacier, Taan Fjord

Tyndall Glacier, Taan Fjord

by | Jul 15, 2020

Tyndall Glacier flows to the head of Icy Bay, about 160 miles (258 km) east-southeast of Cordova and 68 miles (110 km) northwest of Yakutat, Alaska. The glacier was named by members of the New York Times Expedition of 1886 for John Tyndall, 1820- 1893, a British physicist and natural philosopher.

Taan Fjord is on the east side of Icy Bay, about 14 miles (22 km) north-northeast of Point Riou. The fjord was exposed by the recent retreat of Tyndall Glacier. The glacier is named after the Tlingit native word for “Sea Lion”. The rapid retreat of the glacier destabilized the steep slopes of the surrounding mountains and a massive landslide occurred on October 17, 2015.

The event generated a local mega-tsunami that sheared trees at an elevation of more than 500 feet (152.4 meters) on a peninsula within the fjord. Another massive landslide occurred in Glacier Bay National Park on June 28, 2016. Events such as this happen maybe three to five times per year around the world, and Southeast Alaska is the global hotspot. 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.
