However, ice caves also exist in warmer climates.

Most of these caves are what is known as cold traps.
The ice inside the cave also acts as a buffer that helps stabilizes the temperature inside the cave.
Sure, it melts some ice, but the ambient temperature inside the cave stays pretty much constant.
The cave stretches for more than 42 kilometers.
The cave remains relatively ice free during fall and early winter.
During this period, chilly winter air enters the cave and lowers the temperature of the rock walls.
A similar phenomenon is seen atCoudersport Ice Minein Pennsylvania.
Its a small pit, where ice forms only during the summer months, and melts away in winter.
