A ditchless heather covered bowl barrow with gently sloping sides. Its diameter is 16.0 metres and its height 1.9 metres. There is an irregular excavation hollow in the top of the mound which has an approximate diameter of 3.0 metres and a depth of 0.8 metres.


A flint scraper has been found in the vicinity of mound, and a cup-marked stone and piece of calcinated bone have been recorded from the mound itself.


The monument is thought to probably be the landmark known as 'Cronk yn Yeul' mentioned by the Vicar John Bridson in Marown Parish Register of 1780.
