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.

Even in the brief 10-year time that I've been a photographer, changes to our glaciers here are noticeable. It's so sad.

1. Neat, and bad news at the same time

2. I have an issue with the Muir and Carroll Glaciers being attributed to Climate Change

Between 1760 and 1780, the whole of Glacier Bay (which Muir and Carroll are a part of) was under ice right to the mouth. By the 1850's, it had retreated almost half the length of the Bay and this was during the later stages of the mini ice age that ended around 1850. It has continued to retreat since then, most of it by the early 1900's. Are we seeing climate change here or just a natural retreat?

Here's an image from the USGS that gives a visual depiction of what I'm talking about above.

3. I'm not familiar with those glaciers,

so can't opine one way or the other.

I'm most familiar with Portage Glacier, Worthington Glacier and Exit Glacier, which are mountain glaciers, not tidal, so there may be a different dynamic at work.
