From Wikipedia

Morne Watt or Watt Mountain is a mountain consisting of one or more stratovolcanoes at the south end of Dominica in the eastern Caribbean Sea. With an elevation of 1,224 m (4,016 ft), it is the third highest mountain in Dominica after Morne Diablotins and Morne Trois Pitons. The mountain is home to the Boiling Lake and Valley of Desolation thermal areas, both of which are the best-known volcanic features in Dominica and major tourist attractions in Morne Trois Pitons National Park.
