Overview
Rocky Mountain bighorn (Ovis canadensis canadensis) are the iconic subspecies of North American mountain hunting — massive, dark-bodied rams with heavy, broomed horns that curl past the eye into full or greater-than-full curl in mature animals.
Identifying Features
Largest bighorn subspecies; dark gray-brown body with cream-white rump patch and nose; horn color is amber to dark brown with deep, wide curl
Hunting This Subspecies
Most Rocky Mountain bighorn seasons run September through December. Early-season rams are on high alpine summer range; late-season hunting locates rams on winter range below timberline.
