Over the past several years, the U.S. Geological Survey has been shooting a “Repeat Photography” project in various locations to show how glacier ice has been retreating over the past century. Using photos from the late 1800s and early 1900s as references, photographers are rephotographing those same scenes to show how things have changed (and are changing).

Locations covered by the project so far include national parks and forests in Alaska and Glacier National Park in Montana. Montana’s park was covered with 150 glaciers back in the 1800s, but today only 25 of them remain.
Here’s a 3-minute feature National Geographic made about the project in Montana:


Here are some before and after photos published by the project so far:

Muir Glacier and Inlet, Alaska, 1880s and 2005

Muir Glacier and Inlet, Alaska, Mid 1890s and 2005

Carroll Glacier, Alaska, 1906 and 2004

Pedersen Glacier, Alaska, ~1930s and 2005

Grinnell Glacier Overlook, Montana, 1920 and 2008

Grinnell Glacier, Montana, 1926 and 2008

Iceberg Glacier, Montana, ~1940 and 2008

Glacier National Park in Montana is expected to be glacier free by the year 2030 if present warming trends continue.
