The initial discovery of this mineralized, brecciated fault zone cutting the Clough Quartzite is unknown, but it was mentioned by Elwell (1940):
After this it may have become more popular, as Zodac reported in 1948:
A letter from Mr. Smith gave us the following information on his find:
"Last year, four of us Wallingford boys went to the West Stafford locality where we found a large rock with a deep crack in it. With the aid of a crowbar and sledge hammers we pried it open and to our surprise found a cavity inside that was just full of these crystals."
Other minerals found at the locality are limonite (brown stains on quartz which spoils many crystals), muscovite as tiny flakes in the quartzite, and tiny rock crystals in quartz veins.
3 valid minerals.
This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.
