Thank you @livinguktaiwan. I've only just moved over to hive from steemit, I had gone offline for a couple of years and things have very much changed in that time. Thank you for the tips, I have gone and joined the community! 😊
It was a long way to go but sometimes it is about journey too. We stayed for a week and explored the whole area, so it was really nice. But yes, the trip was planned just to see these rock formations.
I believe the damage occurs more from Mother Nature herself. Trees and plants start growing in the crevasses and overtime cause these breakaways. Not knowing when a column may drop, it is still rather risky. I'm not sure how often this occurs but they are mighty impressive!
