Thanks Emma. I can only assume Rhiannon was off with her fairies that day as the MAGIC map doesn't seem to show any long barrows near Elkstone, and nothing at the original grid reference. I have renamed the site according to this http://magic.defra.gov.uk/rsm/31934.pdf
and your photos are now here http://www.themodernantiquarian.com/site/2002
if you want to add any further notes.
Thank you,
TMA Ed.
