There’s a nice stream that feeds into a river near a family member’s home in northeast Ohio. It’s got crystal clear water and a gravel stream bed - the kids love to flip over rocks to find and catch crayfish. On the opposite side of the bank is a sheer wall of sandstone about 20 feet tall. If you stand there for any length of time, you can hear it cracking and every 30-45 seconds you’ll hear (and maybe see) a small rock or a pebble come down and splash into the water. (It’s been doing that for decades or longer and nobody has ever seen anything larger come down so I’ve always felt it was perfectly safe to be on the opposite bank)
