St. Kitts and Nevis are of volcanic origin. In the northwest of St. Kitts is Mt. Liamuiga (also called Mt. Misery), the island's highest peak at 1,156 m (3,792 ft); to the south and west of Mt. Liamuiga are 210-m (700-ft) cliffs that drop straight to the sea. On the southern arm of the island lies the Great Salt Pond. Nevis's highest elevation is the central peak of Mt. Nevis, at 985 m (3,232 ft); it is usually capped in clouds. There is a black sand beach on the northwest coast.
