Yuma Crossing was a very important area along the Colorado River which aided in trade and communication between New Spain and Alta California during the Spainish Colonial Period. It was discovered by Spanish Explorers, who gave it its name. They saw how the Native Americans had used natural elements to aid them in crossing the river.
Yuma Crossing was once a vital part of the Colorado River. It is located in Yuma, Arizona. The river was so wild that it was often impossible to cross, except for at the Yuma Crossing. The waters were much calmer there, and many Native Americans had discovered a natural way to get across. Spainish explorers, led by Hernando de Alarcon and Melchior Diaz were the first Europeans to arrive. In 1540, explorers traveled upriver and the Spainish discovered commuinites. Yuma was one of them. The name was actually coined by the Spainish. Many people came to the area and began building missions. The Yuma Crossing was later opened up to all, and was vital in the Spainish settling upper California.
