Seaham

Seaham is a Carboniferous coal measure spoil heap, which was dumped in front of magnesium limestone cliffs at the old Dawdon Colliery. The reserves are so extensive that they have provided years of interesting collecting from spoil, which is gradually being washed by the sea. The colliery closed in 1991, but the tall cliffs of spoil continue to yield well-preserved plants. Carboniferous, Spoil, Cliffs, Foreshore, Rating: ♦♦♦♦♦
