Castle Peak lava dome, on the right skyline, was formed about 350 years ago during the last eruption of Soufrière Hills volcano prior to the 20th century. Seen here in 1977 from the Tar River valley on the east side of the volcano, the Castle Peak dome was constructed within a 1-km-wide horseshoe-shaped crater, whose southern wall forms the left skyline. The high point at the left is Perche's Mountain lava dome.
