Last Sunday we went to Cathedral Caverns State Park in Woodville, Alabama. Beautiful rolling hills, farmland and woods betray the fact that under it all is a series of caves formed by millennia of water flowing through huge limestone deposits that were once the bottom of an ancient ocean.
The entrance is very large and has a natural limestone roof that is almost perfectly level. I estimate the opening is 100 feet wide and 30 feet high. Things get a little tighter after you go in. The State of Alabama bought the cavern and some surrounding land in the 60's and made it tourist accessible.
The tour guide called this "flowing rock". It is actually water flowing over a limestone formation. Water carried dissolved limestone over the edge of this horizontal rock and slowly re-deposited the limestone in the shape of this curtain.
In reality the stalactites and stalagmites are not this colorful. They use cool colored lights for the blues and greens and warm colored lights for the yellows and the oranges. In natural daylight, of which there is none in the cave, it would all be gray limestone colored and perhaps a little white calcium carbonate.
I needed a bit of a rest after that hike.
Monday we broke camp in Woodville, AL drove to Twin Lakes RV Park in Cumming, GA.
