Michigan!
A selection of minerals from northern Michigan, including a number of interesting datolites. In all but a few cases, I've tried to post specimens that are actually attributed to a particular mine or locality. Whether it is copper (or even more frequently, datolite) the information somehow tends to get lost... I suppose it's understandable, considering many specimens from the area are quite old, and the habits are not always clearly distinguishable from one location to another....(though I know many a Michigander who would disagree with that last statement...)
