What I can tell you about that part of the desert is mostly knowledge given to me from my Grandmothers. Before The Crack in the Ground appeared, there was no New Frederick Road. That whole area belonged to the Choitll people. My people, the Xchiqua have a long relationship with the Choitll.
The first Xchiqua was a Great Cat called Q'Qeqchi. She wandered the entirety of the Earth and when she came into the desert she encountered the Coyote, this was the first Choitll.
Q'Qeqchi was a hunter so she stalked the coyote into the desert. The coyote was very smart and knew that he was being followed, so he tried to lose her in the darkness, that was when Q'qeqchi took a mighty handful of sand and threw it into the sky creating the stars and the moon that light up the desert at night. So now, coyote tried to confuse her by twisting the earth and the trees and the stars in the sky, making them turn slowly around trying to make her lose her way. Q'Qeqchi became so angry that she threw a giant boulder into the sky. This became the sun and suddenly the whole desert was lit up. Energized by the sun she chased coyote into a small cave. She had him backed into a corner. So Coyote fought for his life. This fight should have been easy for Q'Qeqchi, but every time she tore coyote with her claws, Coyote would give a howl and the hair and blood would turn into another coyote who she would also fight turning into even more coyotes. Pretty soon she was surrounded and if it had not been for her incredible speed, she would have surely been devoured.
Today we have the memories of this encounter and we do not wander into their territory without good reason.
