Depression by the roadside, overlooking Keem Strand. Has been systematically excavated, including by mechanical digger, to provide specimens for sale to tourists. Much of what is offerred locally nowadays is actually South American!
Very little can be found nowadays and collecting is more or less prohibited but amethyst may still be found if one is willing to shift tonnes of overburden.
