We have had good fortune on three occasions to see Rocky Mountain Bighorn Sheep.
Such a little sweetie, in the company of two adult females. The crowd of people who stopped to look initially made the youngster nervous, but he or she (see those horn stubs?…but both genders have horns) eventually grew more comfortable.
Our third encounter was really cool. High on the side of the mountain pass out the east entrance road, we saw two males making their leisure way above the road. When they came to a spot where the cliff came out to the road, they had to come down and traverse some pavement before clambering back up and into the woods.
