Summary

An isolated sea stack on the NW coast of Yell, which is now separated from the mainland by a chasm 55m wide and 40m deep, had traces of a substantial bank along its landward lip when first observed by Raymond Lamb in 1971 (1976, 153). No trace of this bank is visible on the available satellite imagery, which shows that the upper part of the sloping seaward side is made up of grass an rock across an irregular area measuring 55m from NE to SW by up to 40m transversely (0.18ha). Beyond this the rocks dip down to the sea over a distance of another 50m. On the landward side of the chasm two old dykes are visible and Lamb suggested that these related to the use of the headland before it became so heavily eroded and possibly when the stack was still connected to the mainland. Certainly the only way of accessing the stack in its present form would be to land by boat on the rocks on its seaward side. While Lamb speculated that this was an early monastic site, its character is quite unknown.

Interior Features

The impression of one possible rectangular building on the satellite imagery is perhaps more likely to be a reflection of the pattern of outcropping rock protruding through the grass
