Yuma County history page
The following paraphrased excerpts are taken from the above mentioned history page:
"Yuma County is one of four original counties designated by the first Territorial Legislature. It maintained its original boundaries until 1983 when voters decided to split Yuma County into LaPaz County in the north and a new "Yuma County" in the south.
At 5,522 square miles, Yuma County is larger than the state of Connecticut.
Much of Yuma County's 5,522 square miles is desert land accented by rugged mountains. Several river valley regions, however, contain an abundance of arable land which is irrigated with water from the Colorado River.
These valley areas have some of the most fertile soils in the world, having received silt and mineral deposits from Colorado and Gila River floods until the rivers were tamed by an intricate series of dams and canals.
