First pic: On the far right is a mature male stone sheep. Next to him is a not-quite mature male. Then three younger males, probably, because- except for the mating season- males often hang out together.
Females and the young stay together all year.
All of these were also along the edge of the Alaska Highway, near Muncho Lake. And nibbling road salt.
#2 and #3 could be females or young males- I don't remember. At a young age, males are about the same size as mature females, and have horns about the same size. An expert could probably tell the difference by the horns- but I can't.
