Situated in Haliburton County, Ontario, Canada, the Bear Lake locality in Monmouth Township within Highlands East is world-renowned for its Grenville Province skarn geology, where late-stage calcite veins cut through metamorphic rocks. Active collecting since the mid-twentieth century has made this site famous for producing massive, exceptionally well-crystallized dark amphibole crystals embedded in orange calcite matrix.
