This recording was gathered in an ice cave on the south flank of the Medicine Lake Volcano in Siskiyou County, California. This ice cave isn't a cave made of ice, but a lava tube which has filled with ice over time. This happens because during winter cold, dense air settles into the cave and has no way to escape as it is heavier than warmer air and the cave has no outlet. Enough cold air collects in the cave that it remains freezing year round, and as water seeps down through the lava and enters the frigid depths of the cave it freezes, which has nearly filled the cave over time. 

If you'd like to see pictures of the ice cave in which this recording was gathered, check out my Facebook page for the podcast, Sound By Nature. Like, follow, and share it while you're there, and tell me what you think. I would appreciate some feedback as well as suggestions for future episodes.

This was recorded during the ongoing Coronavirus pandemic. I hope this or any of my recordings are able to provide you with a bit of peace during this ongoing crisis.
