St. Kitts, like many of its neighbors, was formed by volcanoes all of which are now dormant. The tallest is the 3,792ft Mount Liamuiga, which is thought to have last erupted some 200 years ago.
In an aerial view, St. Kitts, the larger of the two islands, is roughly oval in shape except for a long, narrow peninsula to the southeast. The circularly shaped Nevis is surrounded by coral reefs and the island is almost entirely a single mountain, Nevis Peak (3,232 ft [985 m]).
