Travel to the land of the Anasazi, the bane of Garcia Lopez de Cardenas, the place where the Paiutes tread and the spot christened by the one-armed man named Powell once upon a time in MDCCCLXXII.

Once there, take the south path called, by another name, "Mountain Lying Down".

After you have traveled from winter to summer within one day and just before the second oasis (which is also the 3rd resting place for the beasts of burden), look for the "Rubik's Cube" off to your right.
