Book excerpt: One of the greatest of Hamblin's southern visitations was in the autumn of 1870, when he served as a guide for Major Powell eastward, by way of the Hopi villages and of Fort Defiance. Powell's invitation was the more readily accepted as this appeared to be an opening for the much-desired peace talk with the Navajo. In the expedition were Ammon M. Tenney, Ashton Nebecker, Nathan Terry and Elijah Potter of the brethren, three of Powell's party and a Kaibab Indian.
