Coldwater Cave "Well"

We were recently hired by John Ackerman to construct a 30" diameter access "well" to a cave that ran 180'+/- below ground surface in Northern Iowa.  This is reported to be the 17th largest cave in the United States and access to it had been extremely limited prior to the construction of this passage.

Here are some pictures of this amazing project (click on any picture to enlarge)
