"Dida'a Hotsa'a" in the Navajo language (Diné) meaning "the edge or top of it is HUGE!"
This is what the Native landowners I know call the area. Last year it became ENFORCED OFF-LIMITS except through Sacred Edge Tours (Natively owned).
*BTW, At the time of this post, I have just ONE opening to join a Private SW Workshop in April. Email me if you are fit and interested in going where others don't! 👍
