Kerlingarfjöll

Kerlingarfjöll is a 1,477 m (4,846 ft) tall volcanic massif in Iceland situated in the Highlands of Iceland near the Kjölur highland road. It is usually regarded as part of a large tuya fissure system of 100 km2 (39 sq mi) in the southern portion of the Hofsjökull volcanic system, although is about 20–30 km (12–19 mi) in diameter itself, and is between 68 and 350 thousand years old predating some of the activity in the rest of the system.

You can feel the heat in some spots. A reminder that Iceland sits on one of Earth's most active volcanic zones.

Follow marked paths in active geothermal areas. The ground can be unstable or concealing scalding water beneath a thin crust.
