Cochrane, Andrew (2005) "A taste of the unexpected: subverting mentalités through the motifs and settings of Irish passage tombs". p.4: "To the north of Cairn T and on the exterior is located K29 or the ‘Hag’s Chair’. This kerbstone has visual imagery on its front and back face. The top of the central part of this kerbstone is believed to be artificially cut to create the chair appearance (Shee Twohig 1981, 217; contra. Conwell 1866, 371)".
Documented in photos and videos taken on site for six years running.
