Algar do Carvão Natural Reserve

The great eruption, known as the Pico Alto, which occurred north of the existing Guilherme Moniz volcanic apparatus, poured its lavas from a great distance. Later, a new eruption, this time basaltic, tore the ground and initiated a process that would lead to the formation of a stromboliano volcano – the Peak of the Coal. In a first phase, by forcing and trying to break the existing trachytic effusion, which constituted a natural barrier of little consistency, it formed the zone of the lagoon and the two vaults on it. Later, in a new attempt of evasion, the basaltic lavas, they broke more to the side the current chimney, leaving to the outside. In its final phase the magma descended into the deepest conduits and the magma chamber, giving rise, this almost instantaneous absence of magma, to the formation of the Algar proper. Very effusive lava spills produced very flowing acidic lava rivers that charred existing vegetation. The dating of one of the fossils then formed gives the Algar do Carvão an age of 2148 (+ or-115 years).

Duration: 1 hour

Stop At: Furnas do Enxofre, Porto Judeu, Terceira Portugal

Furnas do Enxofre

The visitation circuit of Furnas do Enxofre was designed to secure the visitation of this natural monument, allowing on one hand, safe access to all visitors, and on the other, protection of the habitats through the use of rustic material, integrated into the landscape. The circuit through the fumaroles and northern slope zone was adapted to existing paths and complemented with facilitated access. A set of informational panels support the interpretation of natural elements present.
