When the buried soils beneath Cronk Mooar burial mound, 1069.00, were excavated in 1945, six infilled post holes and shallow depressions were found to the north and northeast of the grave. These were  interpreted as the remains of a Neolithic settlement site. 


In the south part of this area, were a series of plough marks and a probable field boundary scratched into the untouched soil; in three places these cut through the earlier post holes. The plough marks and field-boundary ran parallel to the existing land divisions and were regarded as dating to the Viking period.
