The Southern Rocky Mountain Wolf
They were found throughout the Rocky Mountain region from Northern Utah and Southern Wyoming, south through Utah and Western Colorado To Northern Arizona and Northern New Mexico. They then became more and more dispersed going west to Central Nevada and as far south as the Providence Mountains in Southern California.
In size, they varied from medium to somewhat large, similar to the Northern Rocky Mountain wolf. They were 4 feet to over 5 feet in length, averaging about 90 pounds, though they were found weighing up to 125 pounds. They had light buff colored fur, similar to the Great Plains wolf.
The Southern Rocky Mountain Wolf officially became extinct in 1935 from excessive hunting, trapping, and poisoning.
