Such beautiful rock cut design are manmade or natural ?

Definitely natural.

Only natural, sun, wind and water made it

Natural

Natural, of course.

Its natural, and one of mother natures stunning feats.

All natural. Nature at its finest.

In the winter Bryce is high enough to have a lot of snow and ice that freeze and refreeze. In the summer there isn't a lot of rain but what there is had continued over thousands of years. This is all natural and extremely beautiful.

Thanks to all
