Those Bighorns are beefer than you would expect, huh? And check this out:
"Bighorn Sheep zigzag up and down cliff faces with amazing ease. They use ledges only 2 inches wide for footholds, and bounce from ledge to ledge over spans as wide as 20 feet. They can move over level ground at 30 miles per hour and scramble up mountain slopes at 15 m.p.h."
"Combat between rams has been observed to last for longer than 24 hours."
"These animals have a short mating season. The rutting season is from mid-September to late October. During this time the rams have butting contests where they may reach one another at speeds of 50-70 miles per hour and an estimated force of 2400 pounds with a "CRACK" that can be heard for amazing distances in a battle for the ewes; for the rest of the year the sheep usually divide into separate male and female herds."
If you ever go out west to Colorado you can see them around the old mining towns. Check this out:
