Mountain climbers are ametures to these guys! They scale rocks and cliffs like my adorable family of squirrels in our back yard whom I never stop adoring over and amazed how dare devils they are! Wish there was a convienance for me to hike at! But also shouldn't you be worried about mountain lions and such?? O.O Be careful!
Yes, I have seen pictures of them standing on cliff sides on a 6 inch ledge. They are amazing. Since I live in Colorado there are many things to do with the Rockies. Hiking 14ers, skiing, mountain biking. I'm not too worried about cougars. I always carry a knife just in case though.
