. It was the highest point on the island until the mid-1990s, when fluctuating volcanic domes during the 1995–1999 Soufrière Hills eruptions eclipsed the peak in height. The Soufriere Hills volcano is on a destructive plate margin, and is part of the Eastern Caribbean Volcanic Arc. This volcanic arc lies on the Caribbean plate, and has formed by subduction of the North American Plate beneath it. On 17 September 1965 a

expedition in response to an ongoing seismic crisis. MacGregor noted that the peak of what he called Chance's Mountain formed the highest point on the island (3002 feet, at that time). Following discussions with a local resident, Thomas Savage English, MacGregor's mapping confirmed that the region to the East of Chance's Peak summit was a breached volcanic crater. MacGregor called this 'English's Crater', and identified this structure on the geological map which accompanied his report. MacGregor also confirmed English's interpretation, that English's Crater contained the
