The Achateny 'Yair'
The photo shows one of West Ardnamurchan's hidden gems, Achateny beach, which has sands which are only exposed on either side of high tide. We had been there many times before we noticed the yair. It's in the middle distance, a line of rocks running from right to left up the beach.
Bing satellite image. Our research didn't suggest how old these structures are, though one is recorded from the 12th century. My guess is that the idea is so simple and so useful that the yair is probably ancient - but that doesn't tell us anything about this particular one.
A paper describing Scottish yairs is here.
