(ND 1162 5384) Mound (NR)

OS 6" map, Caithness, 2nd ed., (1907)

In the angle formed by the confluence of the Olgrimbeg Burn with the River Thurso and about 1/4 mile NE of Leosag farm is a low hillock evidently containing the remains of a broch. It has long been under cultivation and is much spread out. The diameter is about 95ft over all and the maximum height, 6ft. No part of the structure is visible.

RCAHMS 1911, visited 1910.

A great many human bones were found in this mound some years ago.

Name Book 1872.

This mound, 22.0m in diameter and 1.7m high, is featureless except foor a few loose stones on its summit. It closely resembles the horned round cairn at the N end of Loch Calder (ND06SE 9) prior to its excavation, and its situation, on marshy haughland, is similar; it may well be a chambered cairn.

Visited by OS (J L D) 18 April 1962.

(ND 1162 5384) Cairn (NR)

OS 6" map, (1963)

A probable cairn in undulating haughland. It is visible as a turf-covered featureless mound, 1.1m high and about 26.0m NNE-SSW by 22.0m transversely, which merges imperceptibly with the surrounding ground level. Loose stones grouped at the top of the mound are possible remains of a fairly recent marker cairn; otherwise no stones are visible.

Visited by OS (J M) 10 November 1981

Cairn, 'Leosag'. Diameter: 22m. Circular grass-covered mound 1m high.
