Not to be the mineral police but this is not MacFallite it is Orienite, look at page 153 in the book, Mineralogy of Michigan by E.W. Heinrich updated by George Robinnson. Russell MacFall was a friend of the family and I knew him and collected with him as a kid , my father help get testing done on MacFallite to get it listed as a new mineral at Purdue University (the testing).I have a few specimens from Russ himself, there maybe some Macfallite the Orienite is setting on but the orange crystals are not MacFallite. I'm also a friend of Dr. George Robinson and have been collecting in the Keweenaw for over 50 years now.
