Summary of geological interest

North of the village near the road junction at Bowles Farm were two glacial erratic boulders hidden in the grass by the red post box. They were of great interest because they were both igneous rocks of different types. Sadly they have now been removed. Their whereabouts is unknown.

One was a 60 centimetre (2 foot) long angular boulder of fine-grained basalt and the other was a rounded boulder of a coarser-grained igneous rock of similar size that may be syenite.

On the village green (TL 737408) is a round sandstone erratic boulder (80cm x 60cm x 30cm), thought to be of Spilsby Sandstone from Lincolnshire.
