1620 years ago, corresponding with the Steel Dust series of pyroclastic deposits on the western flank. The Mansion Series of pyroclastic deposits and andesite with basalt layers occur on the northern flank, along with mudflows. This volcano has a crater 900 m wide and 244 m deep, plus two distinct parasitic domes consisting primarily of andesite, Brimstone Hill and Sandy Point Hill which is coalesced with Farm Flat. Brimstone Hill is noted for having limestone on its flanks, which was dragged upward with the formation of the dome 44,400 years ago. Mt. Liamuiga partially overlays the Middle Range to the southeast. This Middle Range is another stratovolcano 976 m in height with a small summit crater containing a lake. Next in line is the 900 m South East Range, 1 Myr in age, consisting of four peaks. Ottley's dome and Monkey Hill dome are on the flanks, while the older volcanoes represented by Canada Hills, and Conaree Hills lie past the airport and Basseterre on the southeast flank. The Salt Dome Peninsula contains the oldest volcanic deposits, 2.3–2.77 Myr in age, consisting of at least nine Pelean domes rising up to 319 m in height, which includes Williams Hill and St. Anthony's Peak. History During the last ice age, the sea level was up to lower and St. Kitts and Nevis were one island along with Saba and Sint Eustatius (also known as Statia). St. Kitts was originally settled by pre-agricultural, pre-ceramic "Archaic people", who migrated south down the archipelago from Florida. In a few hundred years they disappeared, to be replaced by the ceramic-using and agriculturalist Saladoid people around 100 BC, who migrated to St. Kitts north up the archipelago from the banks of the Orinoco River in Venezuela. Around 800 AD, they were replaced by the Igneri people, members of the Arawak group. Around 1300 AD, the Kalinago, or Carib people arrived on the islands. These agriculturalists quickly dispersed the Igneri, and forced them northwards to the Greater Antilles. They named Saint Kitts "Liamuiga" meaning "fertile island", and would likely have expanded further north if not for the arrival of Europeans. A Spanish expedition under Christopher Columbus arrived and claimed the island for Spain in 1493. The first English colony was established in 1623, followed by a French colony in 1625. The English and French briefly united to pre-empt a Kalinago ambush. They massacred the local Kalinago, and
