Leaving San Xavier Mission in the autumn of 1775, he traveled with the second Anza Expedition until reaching the Yuma area. From there, he traveled with two Yuma Indian companions through California, re-visiting the San Gabriel Mission. After exploring the Mojave and Colorado Rivers, they crossed northern Arizona to the Hopi mesas and back, returning to San Xavier Sept. 17, 1776.
