Porous Lava Rock on Black Sand Beach Vik Iceland
A porous lava rock sits among its more solid volcanic brethren in the black sand of Reynisfjara Black Sand Beach in Vik, Iceland on the south coast. Dyrholaey volcanic basalt rock arch is visible in the distance as it extends into the sea, surrounded by the Reynisdrangar volcanic basalt rock "sea stacks". Photographed on a cloudy October afternoon.
