Wow! I've been in caves before, but nothing like those! Very cool! Awesome pics, by the way!

Some years ago, we went into a different kin of cave; well, actually, it wasn't a cave at all, but a lava tube! You should try one of those; it's very interesting, and at the back end, before it disappeared underground, you literally had to crawl to get to the above ground end! Turn out your light, and it was complete darkness. You couldn't see your hand in front of your face. That lava tube was near Bend, Oregon.

Thanks for sharing your awesome cave adventure! Take care!
