A limestone/marble quarry located on the northeast corner of Bald Mountain, Jefferson County, Montana. This was opened in the mid-eighties as a source for calcium carbonate and lime; currently not being operated but slated for re-opening. Minerals found here include calcite (strontian), diopside, grossularite, vesuvianite, and several yet to be identified (currently - 2005 - being worked on).
