Don Knowles

Don E. Knowles was born in Michigan(?) on December 14, 1937. He served in the US Navy in Vietnam in the late 1950s. He was the proprietor of Golden Minerals in Golden, Colorado, and was an avid field collector, especially favoring Colorado localities. An article on Colorado barite localities by Barbara Muntyan, published in 1998 in Rocks and Minerals, stated:

"Several years ago, two collectors from the Denver area, Chuck Baldwin and Don Belsher, purchased the [barite crystal] claims at Hartsel to ensure that this area would remain open for hobbyists. The claim was allowed to lapse and was refiled in 1995 by Don Knowles of Golden Minerals in Golden, Colorado, who then worked it as a commercial specimen-recovery operation. Digging slightly away from the two big cuts, Knowles located a large zone of barite crystals displaying a distinct color zoning in alternating bands of golden-yellow and gray-blue. In addition, nearly all the crystals display a truncation on the usual spear-shaped termination. A considerable quantity of fine single crystals and groups has been collected by Knowles, showing that the Hartsel deposit is far from exhausted."

Don Knowles distributed many specimens of Badger Creek (Howard, Colorado) amethyst, and green fluorite from the Robertson-O'Donnell-Pollack pocket on Mount Antero, Colorado. He also dealt in worldwide minerals. He died September 12, 1997 in Golden, Colorado and, by virtue of his status as a veteran, is buried in Fort Logan National Cemetery in Denver, Colorado.
