One of the largest active volcanoes on Earth, Mount Erebus reaches nearly 4 km above sea level. It is famous for its persistently active lava lake. Hot gasses moving up through cracks and fractures in the volcanic rocks surrounding the Erebus summit have resulted in an intricate system of ice caves all over the mountain.
Rock formations formed by explosive volcanic eruptions between six and seven million years ago are chiseled by erosion. Uniform in shape, the formations vary in height from a few feet to 90 feet throughout the 4,000 acre monument.
This wonder is also the site of the ancient city of Hierapolis. Some of the old tombs in the city's necropolis have become part of landscape.
