A horror film where college students go on college break at an older house in the desert. They awaken an Native American ghost that kills everybody besides one of the female college students who’s wearing an Native American pendant. Two college students, who I believe were twins, also get buried alive at the end by the ghost.
I also remember a girl walking nude blindfolded for a sorority challenge and the ghost messing with her.
“The Dark Power”(1985)?
A bit earlier than you said but here is the IMDb link.

‘A broken amulet once owned by a Cherokee Shamain unleashes an ancient curse. Tia, a girl of Native American ancestry, and her friends embark on a Spring Break Trip only to find themselves broken down in a very strange town. After the girls start disappearing one by one, Tia begins to question why the town seems so familiar to her…’
Here’s a clip with the pendant she wears:
Some of what you described sounds vaguely like Buried Alive (2007)
