Oregon's Mt. Hood

Disclaimer: It is a touchy subject. Climate Change, Global Warming, whatever..... I don't want to get into the debate of GW and the like, I just want to share an interesting picture and article with you. Seriously, that's it.

Oregon's Mt. Hood

The side-by-side photographs illustrate how Oregon's Mt. Hood has changed over the past Century. The photograph on the left is from autumn of 1984; the photograph on the right was taken in autumn of 2002.

Oregon’s highest peak, Mt. Hood, provides residents of Northwest Oregon with a familiar yet spectacular snow-capped vista. This view is changing, however, as a two degree Celsius warming trend in the Portland Region over the last Century has been accompanied by the seven largest of Mt. Hood’s eleven glaciers have each lost an average of 34 percent of their mass. Sandy Glacier, the large glacier at the center of these photographs, lost 40 percent of its mass over the last 100 years.
