Standout garnet spots in Connecticut

Hand-picked from the full list below, with the reason each one earns a trip.

Case Quarries
Lower Connecticut River Valley Planning Region County
The Case Quarries are one of only three sites in Connecticut where mineral collecting on state land is legally sanctioned, set in the pegmatites of Meshomasic State Forest. The dumps and pegmatite have produced blue and green gem beryl, some crystals reaching 15 cm, along with columbite, monazite, muscovite, smoky quartz, and garnet. Worked for feldspar in the 1930s, the site is now managed by CT DEEP for permitted educational collecting.
Clark Hill Quarries
Lower Connecticut River Valley Planning Region County
Clark Hill in Meshomasic State Forest is a second DEEP-sanctioned collecting site and includes the well-known Nathan Hall Quarry. Its pegmatites carry sharp books of muscovite, large almandine garnet, beryl in colors from yellow through aqua, and the uranium micas autunite and torbernite, along with fluorapatite and pocket microcline. It is one of the few places in Connecticut where the classic New England pegmatite suite can be collected legally.
