The entrance to the cave

Intrepid explorers were rewarded by glimpses of crystal-lined ice cavern.

Crystals, ice columns, and refrozen ice

Using candles for lighting while exploring ice cave. Without candles, it was pitch-black in this cave.

Ice stalactites, columns of ice, refrozen floor of cave, and ice crystals.

The view from the inside looking out of the cave.

The Clean Air Facility where much of NOAA's South Pole Station work is done This facility is used primarily for atmospheric sampling. The samples are analyzed for greenhouse gas content.

A view of South Pole Station

The view of the South Pole and the Antarctic Plateau from the station. The ice here is over 9000 feet thick. The nearest land feature is a mountain range over 300 miles away.
