The Grotte Casteret is a limestone cave, located in the Spanish Pyrenees, inside the Ordesa National Park. [1]
Characteristics
The cave is named after the French caver Norbert Casteret. The cave is around 500 metres long and up to 35 meters deep. [1]
The cave is characterized by the fact that water flowing into the cave freezes instantly at the entrance. This makes the Grotte Casteret a rare ice cave. These are particuarly rare as they rely on delicate microclimates. The water freezes instantly as the ground is not frozen, so water seeps into the limestone. The cold air from the mountains is trapped in the cave and remains there throughout the year. The water from the limestone then frezes as it drips into the cave, which creates huge icicles and columns of clear glass ice. [1]
