Balanced Basalt Cairn on Madeiran Coast

A carefully constructed rock cairn made of smooth, rounded basalt pebbles stands prominently on a rocky beach on the northern coast of Madeira, near São Jorge. The image captures the distinct volcanic geology of the island, where the Atlantic Ocean has polished the dark stones into smooth cobbles known locally as 'calhau.' The serene composition contrasts the stability of the balanced stack against the vast, overcast horizon of the sea.
