Balanced rock surveyed on Sachem’s Knoll

A balanced or “perched” rock (or possibly a drum rock similar to one in Warwick) that may have been placed by aboriginal people sits on a bedrock outcropping in private property on the east side of Route 136 (Market Street) across from King’s Rock.

Used as a calendar rock, it may have been used to mark celestial events like the vernal equinox and the position of the stars or possibly to signal events held at that location.

(Above, center) The Knoll is high enough that the turbine blades of the Allens Avenue Water Treatment Plant can be seen with the naked eye from atop Sachem’s Knoll. (Above, right) Several rocks have been placed under the boulder to keep it from rolling.
