Another new word for us is "speleologist," which means "cave scientist." These folks say South Dakota is one of the premier cave regions in the world boasts some of the longest and most interesting caves. Most of the caves in this region -- like Ice Cave -- are formed of limestone, and there are in excess of 100 caves in the Black Hills.

Did we mention that people of all ages participate in the Moon Walks? For those who think they'd like to hike the entirety of a big cave, that sounds like fun! But be prepared to spend a few weeks there, because some of these caves are huge! For example, Jewel Cave -- depending on who's counting and when -- is the second longest cave in the world. At last count: more than 120 miles long!

Preparing for the return trip!

Likely a discussion about caves.

One of our visitors has commented about caves in the Black Hills, noting:

"There are FAR more than 100 caves in the Hills. Try closer to 400...that we know about. I ought to know...with my friend Dean, we have discovered more than 70 new ones. We have been to virtually all of the known ones,as well."

For Carter's full comment, go to COMMENTS at the end of our July 16, 2009, posting about caves on Black Hills Journal.

Stopping for a rest -- and a photo!

This would appear to be a family outing for these folks -- and that lad on the lap is probably the youngest caver of our group.

We learned that caves are a valuable habitat for a variety of animals. And while caves seem to have remarkably constant temperatures, it's thought that the cool temperatures are contributing to the White Nose Syndrome that's decimating the bat population in the eastern United State. We've even read about plans to heat some caves to enable to bats to stave off the fungus that's already taken a heavy toll.

While the Moon Walkers came to the cave en masse, we retreated at our own leisure and separately.

As we neared the end of our Moon Walk to Ice Cave, daylight was quickly declining. Many thanks to Amy Ballard, Bradley Phillips, and the many other folks of the U.S. Forest Service who made this and other Moon Walk outings possible.
