The Dominguez-Escalante expedition was the first on it, traveling from Utah Lake to present-day Scipio. Jedediah Smith traveled most of it in 1826 and 1827, and other trappers, including Ewing Young, Kit Carson, and Peter Skene Ogden, followed. John C. Fr?nt mapped the country up to Utah Lake in 1844, and in 1848 Miles Goodyear took a pack train over the entire Salt Lake-Los Angeles route.
He left Cuba for Mexico in 1519, arriving first in the Yucatan Peninsula, and then going inland, and conquering the Aztec Empire by 1524, after which he moved on to Honduras between 1524 and 1526. He returned to Spain in 1528 and then came back to Mexico in 1530 before finally going home to Spain in 1541.
