The name Tʼáá Bííchʼį́įdii was the nickname of an Anglo storekeeper named J.B. Tanner who worked at a trading post in Aneth. The nickname means "just like a devil" in Navajo and was given to him by the local community due to his greedy business practices. He also worked in Yah-ta-hey, New Mexico, leading the Navajo to use the same name for both towns.
