There is an unpublished report by Anthony Brown (Northern Boggarts), but unfortunately I do not have a copy of this, and neither does the British Caving Library.
Brown, A. (2013) Scoska Bone Hunt, 10 July 2013 Unpublished Report.
In 2014 Tony Brown obtained a radiocarbon date on a human finger bone found in the cave (presumed to be from the same skeleton) which showed that the individual died in early medieval times around 700-800 AD.
Ladyside Wood Resurgence is also mentioned in DCA Newsletter 98 p.2, in connection with a dye testing experiment. It seems to be somewhere upstream of Magic Mushroom Resurgence.
