The mound is the classic oval shape of a Drumlin, with a blunt end and a tapered end showing the direction of ice flow. The mound is approximately 3 metres high, 45 metres long and 18 metres wide.
Drumlins are usually found in swarms but this appears to be a solitary example in a housing estate not far from the TT mountain course.
In prehistory the mound was use as a cemetery and archaeologists have found the remains of at least 11 people who were interred between between 3300 BC and 1800 BC.
