Operation Ice Bridge is a NASA mission to monitor the changes in polar ice. The program was started in 2003. Here are some photos that NASA took during their time over Alaska.
Miles Glacier, near Cordova, Alaska. Cordova’s “Million Dollar Bridge”, was officially known as “The Miles Glacier Bridge”. The glacier terminates at Miles Lake, which has formed in the past 100 years.
