This summer, Glacier Park Magazine editor Chris Peterson undertook a photographic project to take photos of Montana's Glacier National Park over 100 consecutive days, starting on May 1, 2009, for a traveling photo show in 2010 to commemorate Glacier's Centennial.

He used a mix of film and digital cameras, including an 8 by 10 field camera, a Kodak Pocket Vest camera, circa 1909, and a Speed Graphic, among others.

His idea was to use the cameras that would have been used over the course of the Park's 100 years. While Chris was kind enough to share some of his photos below, you really should check out his whole set of 100. All photos and captions are from Chris Peterson. (24 photos total).
