Yesterday we went cave exploring. In Wisconsin just west of Mt. Horeb is a place called Cave of the Mounds. It is an amazing place. Originally a lead mine, the miners blasted one day and it opened up this Large cavern (cave) it is really an amazing site. These formations (stalagtites, stalagmites, colums, cave bacon, ect) only grow at a rate of 1/4" every 100 years... if I remember correctly. When you look at these pictures.... remember that fact... it will blow you away!
