The southern end of the elongated Mount St. Catherine volcanic complex on the island of Grenada is seen here from the Southeast Mountain area. The island is composed of five Pliocene-to-Pleistocene volcanic centers, the youngest and highest of which is 840-m-high Mount St. Catherine on the northern end of the island. The most recent activity originated from a group of young maars, tuff rings, and scoria cones extending across the length of the island. These include Grand Etang crater, which lies near the crest of the skyline ridge.
