An ice cave is a natural formation where ice accumulates and remains frozen throughout the year. These caves are typically found in mountainous regions or glaciers, where the temperature is consistently low. The ice can take various forms, including large ice blocks, icicles, and frozen waterfalls. Ice caves often feature stunning blue hues due to the way light refracts through the ice. Visitors to ice caves can experience unique geological formations and learn about the processes that create these environments. They are often part of larger systems, such as glaciers or volcanic formations, and can provide valuable insights into climate change and the Earth's history.
