David A. Prevedel was a Geographic Information Systems (GIS) and Remote Sensing Program Coordinator for the Intermountain Region of the Forest Service in Ogden, Utah. He was a range conservationist on various forests in Montana, Utah, and Wyoming.

Albert F. Potter was an Arizona rancher who was hired as a Utah grazing expert in 1901 where he worked to designate areas as forest reserves. Potter took photographs of about 400 locations during the summer of 1902. Some of these photographs are available in this collection. Potter worked to find a balance between reserving land and public use of that land.

As Prevedel and Curtis (2005) write, "In 1901, Albert F. Potter was hired as a grazing expert and in 1902 completed a survey of the potential Forest Reserves in Utah. During the summer of that year, he traveled over 2,000 miles of which approximately 1,650 were on horseback. He visited 42 towns seeking input on the designation of forest reserves and refined the boundaries outlines by the GLO. Potter's diary and report of this survey survive intact today.

"Albert Potter also took photographs. From the numeric sequence, he took around 400 exposures during the summer of 1902. 67 photographs survive in his report and an additional 59 with some duplication have been found in Forest and special collection files. Several of these have been relocated and re-photographed for inclusion in this document.

"By 1906, Potter was Inspector of Grazing with the newly formed Forest Service and went on to become Assistant Forester in 1907 and Associate Forester in 1910. He was the agency's first Chief of Grazing. A close associate of Gifford Pinchot and later Henry Graves, he was the first westerner to hold a high post in the U.S. Forest Service. He organized the service's grazing policies, regulations, and procedures. Seeking cooperation, he assured that the management of western ranges was shared with the stockmen while still retaining the final decisions as to the principles and details of operation in the hands of local Forest officers."

Lincoln Ellison was born in Portland, Oregon, grew up in California, and worked for the United States Forest Service throughout the western United States during the 1930s-1950s. He was the director of the Great Basin Experiment Station in Ephraim, Utah, and later moved to Ogden, Utah, to manage the region's range research program.
