Mount Scenery

Saba

Stratovolkan · Netherlands · 887 m

Mt. Scenery, the summit lava dome of Saba volcano, is seen from the airport on the NE side of the island.  The sun-dappled slopes in the foreground are the surface of a large andesitic lava flow that descends the NE flank of the volcano and forms the Flat Point Peninsula, on which the airport was constructed.  A steep switch-backed road extends from the airport to the village of Lower Hells Gate (center).  Saba is the northernmost active volcano of the West Indies.

Saba, the northernmost active volcano of the West Indies, is a 5-km-diameter island forming the upper half of a large stratovolcano that rises 1,500 m above the sea floor. Its eruptive history is characterized by the emplacement of lava domes and associated pyroclastic flows. The summit, known as Mount Scenery (or The Mountain), is a Holocene lava dome that overtops a major collapse scarp that formed about 100,000 years ago. Flank domes were constructed on the SW, SE, E, and NE sides of the island near the coast. A large andesitic lava flow entered the sea on the NE flank, forming the Flat Point Peninsula. The village of The Bottom overlies pyroclastic-surge deposits that contain European pottery fragments and were radiocarbon dated at 280 +/- 80 years before present. The village was settled in 1640 CE on grassy meadows on the volcano's flanks reflecting initial vegetation recovery following destruction of tropical rainforests by pyroclastic flows and surges. Lava dome growth may also have occurred during this SW-flank eruption.

Mount Scenery is a dormant volcano in the Caribbean Netherlands. Its lava dome forms the summit of the Saba island stratovolcano. At an elevation of 870 m (2,854 ft), it is the highest point in both the Kingdom of the Netherlands, and, since the dissolution of the Netherlands Antilles on 10 October 2010, the highest point in the Netherlands proper.
