The Repeat Photography Project

It was a lightbulb moment: Why not use the old photos to create a timeline of the morphing glaciers, and add new photos every year? | In 1997 Lisa McKeon, a physical scientist with the United States Geological Survey who works in the park came across a pair of historic photographs depicting the glaciers she studies. | Over the years, countless photos of the majestic park have been snapped, and many of those have become part of the park's official archive, spanning over a century. | The Repeat Photography Project was born.
