Profesor John W. Webster of Harvard University operated this quarry for specimens and described vesuvianite from this locality in an article in American Journal of Science in 1848. It was later worked by Mr. Goodall of Sanford whose family owned a famous mill in the town and where there was once a private natural history museum.

The locality consist of a calc-silicate granofels (3-4m thick) with minor marble bounded on all sides by the Lyman Pluton (an acidic non-foliated biotite granite).

Several minerals here are fluorescent: scheelite, powellite, meionite, titanite, fluorite, and some of the calcite.
