I spent the last few years of my decades of employment in resource management with the Alberta Environment ministry, AFS and I have seen a number of rams like that in inaccessible places where only a helicopter can get to and land. These, were in an area fairly close to where that old boy lived, but, while some hunting can be done there, much of the area is Canadian National Park land.
I also once saw a RM Goat. a fairly common species here in BC, in that AB region and he had honkin' great horns that looked longer than his whole head; he was bedded in a scree field that was above a 1000 ft. drop and was totally in command of all he surveyed.
