Photographic Archive 1995 - 2001






The Cloud Peak Wilderness automatic photographic monitoring system was installed atop Grouse Mountain in June 1996.  The camera viewed Mathers Peak to the west until October 2001. 

Photographs were taken at 09:00 and 12:00 daily from 1995 through 2001.  Monitoring frequencies decreased to once daily (9:00) during winter months.  Over 3,300 35mm color slides of the Mathers Peak Vista were reviewed to develop the provided historical photographic archive.

In April, 2001 the Wyoming Department of Environmental Quality installed a high-resolution digital camera.  The camera views Hunter Mesa to the southwest.  No Hunter Mesa Vista images are included in this historical archive.
