Lac Flammarion is a volcanic crater lake in Guadeloupe,[2] which straddles the communes of Gourbeyre and Capesterre. It is situated at an altitude of 1,103 metres (3,619 ft), and measures 90 metres (300 ft) by 70 metres (230 ft).[1]
The lake is entirely filled by rainfall, which is usually about 8,000 millimetres (310 in) per year. The water is acidic with a pH ranging between 4.5 and 5. Its temperature ranges between 18 and 19 °C.
Flammarion is free of vegetation, but rather rare species that prefer the acidic conditions grow on its shores, such as Blechnum l'herminieri , Isachne rigidifolia and Juncus guadeloupensis , an endemic species of rush.[3]
The crater was named by the famous alpinist Mr. Camille Thionville, chef du service de l'Enregistrement et des Domaines.[2]
