The Southern rocky mountain wolf (Canis lupus youngi), also known as the Southern rockies wolf, the Southern rocky mountain gray wolf, the Southern rocky mountains common wolf, and the Great basin gray wolf, was a subspecies of the gray wolf, (Canis lupus), that used to roam in the regions in and around Nevada, Arizona, Utah, and Colorado. The subspecies was named after Stanley P. Young. They were hunted by humans and became extinct in 1935.[1]


The Southern Rocky Mountain Wolf can grow up to 5 feet in length and weighed about 120 pounds which makes it larger and more formidable than today's more common Gray Wolf. Their strength and speed allowed these superior hunters to travel in small packs than other wolf species. They also roam the southern area of the Sierra Mountains.
