Dwarves' Earth Treasures Online Museum:
Connecticut Datolites
Connecticut Mine, Delaware, Keweenaw CO., Michigan
Field-collecting Status:  Owned by lumbering company, no treaspassing

    The Connecticut Mine was a western expansion of the Delaware Fissure and like Delaware mine, the Connecticut mine produced very little copper but lot of calcite. There are few types of datolites: the classic ones are are opaque white sometimes with red & orange colors, and most datolites from other spots around the mine dumps are white.  As of August 2014, I found a large rock containing several datolites and I broke it down to extract them. They turned out to be faint orange-colored. :) As of August 2016, the rocks are being hauled away to be used on the lumbering roads.
