The unknown caves of northeast Iowa
February 27th, 2008If you like to travel you should check out the northeast Iowa tourism attractions. There are a few things about the area that are little known except for the locals. For instance did you know that area was full of underground caves? They are formed because the rock around there is mostly limestone and the water running underground in the area easily dissolves this rock forming a cave. The farmers of the area are well aware of the fact as every once in a while a farmer will unknowingly park his tractor over one of these caves and leave. When he returns he finds that implement at the bottom of a sink hole. The weight of the machine having cracked through the thin ceiling of the cave after time vs weight hit the right point. The only way to recover the tractor is to rent a large helicopter and have it lifted out of the hole, not an inexpensive chore. Many of these caves are actually very small and some of them are quite large. Exploring caves is not a big pastime in the area so it is unknown just how many of these caves there are in the area.
