The Friends of Mineralogy (FM) is an organization devoted to the advancement of serious interest in minerals and related activities. It consists of mineral collectors, professional mineralogists and curators of public and private collections. The bond uniting these people is a love of mineral specimens and a desire to spread appreciation and knowledge of minerals. FM was formed in 1970 in Tucson, Arizona. An initial project was the establishment of The Mineralogical Record. The FM has had a close and continuing association with The Mineralogical Record and with Rocks & Minerals Magazine. One of the organization's important activities has been support of the two magazines as vehicles for the preservation and dissemination of mineralogical information. This website is for the Pennsylvania Chapter of the Friends of Mineralogy

Check out the July-August 2011 issue of the Mineralogical Record (vol. 42 no. 4). It contains an excellent article on the Wood Mine in Lancaster County, Pennsylvania, written by Wendell Wilson. There are several photographs of amazing brucite specimens. Also included on page 314 is a photograph from the May 2010 FM-PESA field trip to the Wood Mine. George Loud is standing on the side of a trench. Is that Arnold Mogel in the trench? Who else can we recognize in the photo?

A book on the history of the Cornwall Mines in Lebanon County, Pennsylvania was written by Bob Donley from Cornwall, Pa., and Charles Boyer, a former Cornwall miner.
