Arizona Gold Mine - Yuma
From Wikipedia, the free encyclopedia:
The area's first settlers for thousands of years were Native American cultures and historic tribes. Their descendants now occupy the Cocopah and Quechan reservations.
In 1540, Spanish colonial expeditions under Hernando de Alarcon and Melchior Diaz visited the area and immediately recognized the natural crossing of the Colorado River as an ideal spot for a city. The Colorado River narrows to slightly under 1,000 feet wide in one area. Military expeditions that crossed the Colorado River at the Yuma Crossing include Juan Bautista de Anza (1774), the Mormon Battalion(1848) and the California Column (1862).
During and after the California Gold Rush to the late 1870s, the Yuma Crossing was known for its ferry crossings for the Southern Emigrant Trail. This was considered the gateway to California, as it was one of the few natural spots where travelers could cross the otherwise very wide Colorado River.
