Want to walk through the throat of a volcano?
@nate_dodge: It's a rain forest. Inside a volcano. With a lake at the very bottom. Wild would be an understatement.
This is Algar do Carvão, which translates to Cavern of Coal or coal pit. It's an ancient lava tube or volcanic vent on the Azorean island of Terceira in Portugal. It is part of the Guilherme Moniz volcano (one of the large volcanoes on Terceira), but also belongs to the same system as the Pico Alto and Santa Barbara volcanoes. A volcanic eruption occurred roughly 3,200 years ago and created this lava tube which is lined in basalt. A second eruption roughly 2,000 years ago created several magma chambers that are empty today and open for visitors to explore.
Visitors travel down the volcanic chimney and a tunnel and staircases to access caves below the surface. Walking paths are lit and regularly maintained. At the bottom lies a crystal-clear lake formed by rainwater. This lake's evaporation and the frequent rainfall sustain the flora and fauna that survive on the walls of Algar do Carvão. The cave also has the greatest concentration of amorphous silicate stalactites and stalagmites in the world. As far as we are aware, this is the only place where people can see both the volcanic chimney and the magma chambers without being boiled alive.
