I saw this photo a number of years ago and thought it was amazing. This is a cave entrance in Venezua. (The two tiny objects at the bottom are heliocopters).

I know nothing of the rest of the site, so surf at your own risk, but this photo was taken from among several more on a post on entitled the “7 Most Amazing Caves of Our World” .
This is yet another example of God’s glory displayed in His creation.
