World-wide systematic mineral collector since 1978, mindat contributer since Jan. 2004, focused on the mineralogy of Pennsylvania.

Now with the new and improved Mindat gallery, I've finally decided to contribute specimen pics from my other locality collections and world wide systematics, for localities which could use some additional representation. You can still view ONLY the Pennsylvania specimens by choosing the 'Mineral Name/Photo Title' option under 'Which Order' and typing "Pennsylvania" in the 'Keyword Box'. MRH
