Exactly, Rick, in my photos I show a big horn sheep looking over a cliff at us in a hot spring. When I took my grand daughters there just before Christmas we saw a small herd and they were afraid because of their big horns. I told them I would give them a 100 $ if they could catch one. Of course, they felt better when they found that that is impossible. In my photos I said he (the sheep) will bump you in the but if you are not a good hot springer.
In your photo you show a female and a baby sheep. Females have smaller horns. The females here have larger horns than the species in Yosemite.
