Kaksikute campfire site

Here you can view the blackish brown boulders gneissic breccias. The boulders have been formed 540 million years ago when 10 km North-West of the island the Neugrund meteorite landed in the sea.

The Kaksikute campfire site on Osmussaar island is named after the Twins, the best known of the island's blackish-brown boulders of gneissic breccia. These are no ordinary erratic stones. They are thought to have formed about 540 million years ago when a meteorite hit the sea roughly 10 km north-west of the island, creating the Neugrund crater, now under water. The impact shattered and fused the rock, and later the ice carried pieces onto Osmussaar. Around the site are relict lakes, cut off from the sea as the land rose, and remains of the island's military past. Visits must be arranged in advance, with parking at Dirhami harbour.
