The story behind these mysterious sand murals on Britain's beaches CNN - October 8, 2018
If you've been frequenting the sandy beaches along the rugged, Welsh Pembrokeshire Coast in Britain, you might have noticed some mysterious shapes appearing in the sand.
These intricate murals are beach-based works of art created by local sand muralist Marc Treanor. Inspired by crop circles, the enigmatic formations that occasionally appear in corn and wheat fields, Treanor forges stunningly intricate patterns and pictures by raking wet sand. When he's done, Treanor watches as his hard work is consumed by the crashing waves, but he says that's all part of the experience.
