I cannot imagine anything worse than doing this! It's certainly up there. Not just what you mentioned but also the fact the earth moves. One decent earthquake and what was 14 inches of clearance can go to 7 inches or less. Water tables shrink which removes pressure and that can also cause ground movement. This is happening in Arizona and New Mexico right now from soft drink companies draining aquifers and then trying to shift blame to datacenters and farmers. Very much a roll of the dice. I still find it fascinating to watch. Emphasis on watch. I'm not going in that cave either. Maybe a drone that can both swim and fly accepting I might lose my drone.
