Silvestre Vélez de Escalante

The Domínguez–Escalante Expedition was a Spanish journey of exploration conducted in 1776 by two Franciscan priests, Atanasio Domínguez and Silvestre Vélez de Escalante, to find an overland route from Santa Fe, New Mexico, to their Roman Catholic mission in Monterey, on the coast of modern day central California. Domínguez, Vélez de Escalante, and Bernardo de Miera y Pacheco, acting as the expedition's cartographer, traveled with ten men from Santa Fe through many unexplored portions of the American West, including present-day western Colorado, Utah, and northern Arizona. Along part of the journey, they were aided by three indigenous guides of the Timpanogos tribe.
