The Dave Prevedel photograph collection consists of original and digital copies of documents, reports, maps, and photographs relating to U.S. Forest Service grazing expert Albert F. Potter's 1902 Utah forest survey and Dave Prevedel's rephotography project for the U.S. Forest Service during the 1970s, 1990s, and early 2000s. Included in these documents are copies of Albert F. Potter's original forest survey images, which were the subject of Prevedel's rephotography, as well as a copy of Potter's original forest survey report. Also included are articles about the life and philosophy of Forest Ranger Lincoln Ellison.

This collection offers a snapshot of the origins of the U.S. Forest Service at the turn of the twentieth century and documents how many of Utah's forests have changed over time.

The Collection is divided into four series:

"I. U.S. Forest Service Images" contains Forest Service survey views taken by Potter in or around 1902.

"II. U.S. Forest Service Reports and Photography" contains photographs taken by Potter, Prevedel's rephotography, published reports by Prevedel, and a copy of Potter's Journal from 1902.

"III. Maps" contains annotated maps of Potter and Prevedel's routes and locations of photographs in Utah.

"IV. Digital Material" contains 18 CD-ROMs with copies of photographs taken by Potter and Prevedel, as well as copies of Prevedel's Forest Survey reports.
