Ak'e Ny dzin, or Navajo Oshley, was born sometime between 1879 and 1893. His oral memoir is set on the northern frontier of Navajo land, principally the San Juan River basin in southeastern Utah, and tells the story of his early life near Dennehetso and his travels, before there were roads or many towns, from Monument Valley north along Comb Ridge to Blue Mountain. During the late 19th and early 20th centuries, Anglos and Navajos expanded their use and settlement of lands north of the San Juan. Grazing lands and the Anglo wage economy drew many Navajos across the river. Oshley, a sheep
