If you’re looking for more information about the 2010 Glacier Centennial make sure you check out the Centennial page on the Park’s website.
Kass Hardy, the Centennial Coordinator for Glacier National Park maintains a Centennial Blog which should be a great resource as the fun begins.
Finally, you can also Visit Glacier National Park’s Official Centennial Website at https://www.glaciercentennial.org/.
At the moment all of these pages seem to have similar content but I’m sure they will be updated as the summer season approaches.
