Sint Eustatius is 6 miles (10 km) long and up to 3 miles (5 km) wide. Topographically, the island is saddle-shaped, with the 602 meter-high dormant volcano Quill (Mount Mazinga), (from Dutch kuil, meaning 'pit'—originally referring to its crater) to the southeast and the smaller summits of Signal Hill/Little Mountain (or Bergje) and Boven Mountain to the northwest. The Quill crater is a popular tourist attraction on the island. The bulk of the island's population lives in the flat saddle between the two elevated areas, which forms the centre of the island.
