Cedar Rapids cave

Yesterday I reviewed and listed a new cache in Cedar Rapids that really has me thinking because of what the owner wrote about the location in his description. The cache is called Mosquito Cave and in his description, AB-n-AP says:

After the Civil War, a gang of horse thieves used to run their stolen horses through what is now known as Horsethief Cave. The thieves would enter the cave, located a few miles north of Mosquito Cave, and not emerge until they reached Anamosa - 23 miles away!

I lived in Cedar Rapids for seven years and I never heard about this cave. I wish I would have because I would have loved to explore this. It's hard for me to imagine that horse thieves could fit horses through a labrinth of caves that extended for 23 miles, and it's right there under the Cedar River all the way to Anamosa. If it's true -- and I don't have any reason to doubt AB-n-AP -- that's pretty amazing.
