Happy Cave Week to all those who celebrate.
Which should be everyone. Because caves are awesome.
Even if they give you the claustrophobic heebieejeebies, caves and karsts are great habitats for bats, vital distribution and filter mechanisms for our groundwater, and important settings of stories in many cultures.
Happy Cave Week from Wind Cave National Park! We are home to the world’s sixth-longest cave, with nearly 170 miles mapped. That makes us the third-longest in the United States! Wind Cave is also considered by many to be the world’s most complex cave due to its many passageways lying under about one square mile of land, all tangled together. What’s more, studies of air flow and air volume make us think Wind Cave is likely less than 10% mapped!
