Yuma Crossing

It connected New Spain and Las Californias in the Spanish Colonial period in and also during the Western expansion of the United States.

History
The history of the Yuma Crossing began at the formation of two massive granite outcroppings on the Colorado River. The narrowing of the river provided the only crossing point for a thousand miles, thus making it a focal point for the Patayan tribes, and later the Quechan.
In 1540, well before the British Europeans touched Plymouth Rock in 1620, Yuma's European history began here with the arrival of Spanish explorer Hernando de Alarcón. It was not until after the 17th and 18th century explorations of the padres Kino and Garcés that the crossing came to be used by the Spanish expeditions of Juan Bautista de Anza and others along this route from 1774. This route, sometimes called the Sonora Road, ran from the Spanish Tubac Presidio, in Sonora to Alta California. An attempt to establish missions and colonize the area of the crossing was made by the Spanish soon after but it failed, when the formerly friendly Quechan were angered to the point of a violent revolt that ended the missions, the colony and the use of the land route until the 19th century.

Why this record matters
“Yuma Crossing” is worth following because a concise public description often conceals a longer documentary argument. Here, Yuma, Crossing and historic provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q8061033. The Library of Congress control number is sh88003225. Authority coordinates are 32.729, -114.616. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1850, 1885, 1540 and 1620.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
