Photos a century apart document glacial changes on Mount Baker

About seven years ago, when mountain photographer John Scurlock first saw the 1912 photograph of the south side of Mount Baker, he was smitten with its historical value.

When Dave Tucker, a geology research assistant at Western Washington University, saw the photograph, he was intrigued because it showed the rim of Baker's summit crater.

Later, they kicked around the idea of replicating the photo to create a centennial "then-and-now" set of images that, among other things, would show how Mount Baker's glaciers, including the large Easton Glacier, in the middle of the photo, had shrunk over the past 100 years.
