Greetings from the LooseNatural farm in Andalusia Spain where we currently live through a drought and we are creating swales and plant them with bamboo. Thanks for sharing this video
Interesting. "Bowl Shaped depression" sounds like an impact crater. There are many such depressions in the SE USA in particular. Randall Carlson YTube does some good discussions about this. May have happened much sooner during the Younger Dryas period, 11-13,000 years ago. Watching from the Philippines.
