This is the first pic of a little virtual mini tour of Squire Boone Caverns in southern Indiana. Because the pictures were taken in low light, I had to use a higher ISO, which caused more noise. I'm glad I had Neat Image :)

First, our group had to descend a 73 step spiral staircase to get to the cave floor, which we had to walk back up to get out. Here is a neat looking stalactite...Stalactites hang from the ceiling and are more pointed and carrot shaped. Stalagmites are on the floor and are more rounded and shorter because of gravity.
