A view of the top of the stone The stone is a large glacial erratic of both geological and local importance. Yet sadly it isn't known very well. Geologically the composition is unknown, probably a calcareous grit of some kind. Sources say it comes from a range of places like Oxford, Sunderland and even Scandinavia! There is a very nice ammonite in the centre of the stone which shows it is certainly sedimentary. The 20 ton boulder is the largest erratic of its type in Norfolk. It was moved here during the last ice age when ice picked it up and dumped it here. It is now in a marl pit (http://en.wikipedia.org/wiki/Marl ) just off Peddars way.
