Are you asking if white people ever lied to the native americans?
Anywho, here is what BLM says:
"Navajo interpretation of Valley of the Gods
rock formations: “Rock formations are places
of power in which spirits reside, and the formations
in Valley of the Gods are some of the most
distinctive. These imposing monoliths are Navajo
warriors frozen in stone, who can be appealed
to for protection. They are guardians
whose power and strength aid young servicemen
going to war.” (From Sacred Land Sacred View
by Dr. Robert S. McPherson, Brigham Young
University.)"
