Green Low has been about a bit....one time thought of as a stone circle...then robbed cairn..followed by ring cairn and marked on the map as a cairn circle...
The NMR seems to go with ring cairn...and if it is it’s easily Derbyshire’s best...a well defined grasscovered rubble ring approx 22x20m with a bank 50cm high...a smaller rubble ring is visible in the northern half of the cairn.
Located a few KM west of Mam Tor the ring cairn is unmissable as you walk along the path, starting at SK091 824....800m along.
250m east is a smaller cairn circle 6x8m in diameter and a bit tired looking.
