Residential housing development from about 2000 to 2016 on this hill exposed quartz-mineralized brittle faults, probably related to the Hartford Basin just to the east, cross-cutting the Ordovician hornblende gneiss/amphibolite member of the Collinsville Formation and the Ordovician Bristol Gneiss. Finds were at least along Windsor Court, Tyler Court and Kingswood Road. Some metamorphic mineral crystals were also found in those host rocks. Coordinates are for the summit of the hill.

Turns out Shepard (1837) described loose surface boulders of quartz here (the hill is bisected by the Canton-Avon town line and quartz is likely found on both sides):
A cellular drusy quartz found on Whortleberry-hill [aka Huckleberry Hill] in the south part, of Canton, was used during the last war for millstones. Several acres near the top of this hill are strewed over with large masses of this rock.
