Two parallel quarries and some nearby prospects in generally N-S oriented granite pegmatite dikes about which surprisingly very little has been written, probably because it is not described in Cameron et al (1954) Pegmatite Investigations 1942-45: New England and so did not get into the many collector guidebooks of the 1950s to 1970s. One of the quarries is almost certainly the "new" Wiarda quarry, that Watts (1916) describes as:

located in a feldspar deposit on a north and south ridge on the outskirts of South Glastonbury. Several irregular dikes are exposed, but little actual development work has been done to indicate the continuity of any particular dike or to ascertain the width of the bands rich in feldspar. A good quality of feldspar and graphic granite have been obtained from this property and 2,000 tons were reported as being quarried in 1911.


No other place fits this description. The only descriptions using the name "Simpson" are by Hiller (1967), who writes about the good beryl, muscovite and microcline crystals he collected. This article did not spur much collecting, probably because few people could find it then. Collecting activity increased in the 1990s with the construction of nearby residential roads, and publications such as Betts (1996 & 1999), who mentions good quality aquamarine and "bright blue-green hyalite opal". Scattered but well-formed microlite crystals are also noteworthy as are metatorbernite coatings.
