Nice pictures and nice formations. Caving is super fun. As a kid growing up in California our 4th grade class went on a field trip to the Moaning caverns. That experience left a lasting mark on me and a serious desire to explore to the point I left my wife @stryeyz alone in the dark, in the middle of Cody Cave in BC Canada,  while I went and explored the rest of the cave.  It all ended up fine but she still reminds me of it from time to time.... Needless to say the spelunking bug has a strong bite and that venom can take a person over, but it can be fun, scary, and purely thrilling all at once.
