Grenville -Bear Lake Diggings, nr. Gooderham, Ontario

The "Bear Lake Diggings" are a favourite, easy to get at place for beginners and advanced collectors alike to dig for apatite, titanite, orthoclase and biotite. It is not always easy to find good specimens, though. If you went there and came away empty handed, here are some nice specimens for you! BTW, the primary amphibole found at Bear Lake has been re-defined as ferri-fluoro-katophorite, NOT fluor magnesiokatophorite, NOT magnesiokatophorite and NOT katophorite! Please change your labels! This is the type locality for ferri-fluor-katophorite.

  • These special types of titanites are, arguably, more desired than the regular brown ones. They are a creamy white colour and lustrous. Some people say that they are titanite altered to anatase which would make them pseudomorphs. Others say that they are just titanite damaged by teeny frost fractures. This specimen is a very nice, twinned crystal as you can see by the prominent re-entrant angle. A nice one!
