TECATE, Mexico (AP) — White sage burning, Norma Meza Calles gathers guests at a Mexican wellness resort into a semicircle facing Kuuchamaa Mountain and asks everyone to close their eyes and feel its presence.

"This is sacred to us like a church for you all. The mountain is our healer, our psychologist," said Meza Calles, a Kumeyaay Nation tribal leader who explains that in its creation story a shaman transformed into the mountain. "Here is where we gather strength to live in this difficult world."

Then she calls for a moment of reflection. But the silence is pierced by the crushing of rock. U.S. federal contractors have been blasting and bulldozing Kuuchamaa, which straddles both countries, to make way for new sections of wall along the U.S.-Mexico border.

Indigenous leaders say that in the Trump administration's rush to build border walls, contractors are desecrating Native American sacred places and cultural sites at an unprecedented pace, more than 170 years after the international boundary split the territories of dozens of tribes.
