Block of Hoyt Limestone

This fresh boulder in the Hoyt Quarry was perhaps left by a geology class or an amateur, no one else being interested in the subject or equipped to dress the rock in the field this way. It looks strong, but this rock was not quarried for building stone. Because the rock was pure, it was readily burnt for lime (CaO, calcium oxide) for making cement. There must have been a good wood supply near to make that operation efficient.
