Smooth fracture surfaces at the lava dome: trees, having their roots reach into the tiniest crevaces, are clinging onto the vertical walls like free-climbers.

Methana peninsula, located opposite Aegina Island in the Saronic Gulf of Greece, is the northwestern, still weakly active part of the active Aegean volcanic arc.
An eruption in 238 BC built a small lava dome on the northern tip of the peninsula and was described by Greek and Roman historians (e.g. Pausanias). Methana peninsula is famous for its hot springs and thermal baths, hence its name.

Background:

Methana volcanic system comprises a group of 32 lava mostly dacitic lava domes, whose formation started about 1-2 million years ago. The latest activity was likely around 1700 AD in form of a submarine eruption off the northern coast.
An active hydrothermal system characterizes the area, controlled by a E-W fault system that crosses the town of Methana where thermal springs are found.
