What it is Filled

A large boulder, also called a logan stone or rocking stone, balanced so finely on its base that it can be rocked with slight pressure, usually a natural result of glacial deposition or weathering, occasionally treated in the past as a druidical monument; rocking stones are found in Britain, Ireland, Spain, the United States and elsewhere and are often local landmarks.

Why it exists Filled

Let an agent explain rocking stones and how they form, relay notable examples and folklore from geological and antiquarian sources with attribution, describe their status as landmarks, and distinguish rocking stones from erratics in general, from balancing rocks that do not rock and from megalithic monuments.

May
