Arizona – Ecological Expeditions
Back in the 1880s, the Ecological Expeditions was the most-seen event in Arizona. As dated September 1871 on photographs of an expedition trip through Colorado from Camp Mojave, Arizona. Timothy H. O’Sullivan, a New Yorker took the photograph, who was staying at Camp Mojave at the time.
The people who joined the expedition were hoping to travel entirely across the Colorado River. Through the photograph, we can see that the then Colorado River looked different from what it looks like today, particularly after the construction of the dams in the area by the settlers.
