The eastern part of the Moor was covered by Meare Pool which was formed by water ponding-up behind the raised peat bogs between the Wedmore and the Polden Hills, and coring has shown that it is filled with at least of detritus mud, mainly dating from the Subatlantic climatic period (1st millennium BC). In prehistoric times there were two Meare Lake Villages situated within the lake, occupied at different times between 300 BCE and 100 CE, similar to the nearby Glastonbury Lake Village.
