"[4] Stac Lee is located in the North Atlantic and forms part of the St Kilda archipelago of the Outer Hebrides.

[5][6] Seen from the south, the rock appears as an imposing cliff as broad as high, while from the west it has the aspect of a thin needle with a top bevelled at an angle of 45°.

[4] The stack was climbed in 1969 by conservationists Dick Balharry and John Morton Boyd; then on 31 May 1977 by a party including the islands' then Warden Stuart Murray (who is co-author with Mike P Harris of Birds of St Kilda[7]) and another key researcher of the archipelago, Mary Harman.

After a gannet census visit on 20 June 1985, Peter Moore, documented the gannet-hunters' bothy in an article for a Scottish Vernacular Buildings Working Group publication.

[13] In 2004 about 14,000 occupied nest sites were observed on Stac Lee alone, and this number is thought to have been stable over the previous ten years.
