I didn't actually go on this trip, I just really wanted to post these photos that my brother in law captured on a kayaking trip a few days back. I'll quote what he wrote in a blog attached to them:

"This weekend, while taking a trip out to Apache Lake with my friend Brandon, we encountered one of the few (native) species of large mammals that I had never seen in Arizona (aside from captive specimens). While driving down Fish Creek Hill on the old Apache Trail between Canyon and Apache Lakes (an hour east of Mesa), we noticed a small rock slide coming down the steep mountainside to our right. As we approached it, I craned my neck to see, and saw some desert big horn sheep traversing the steep terrain!

We drove down about a 1/4 mile to where we could turn the truck around. When we drove back up to find them again, we saw about a half-dozen sheep up on the mountain, about 50 feet up. I got out of the truck and trotted over to get a picture. Just before I was going to snap the picture, I looked up the dirt road to see if any cars we coming before I took a couple of pictures. In this quick glance, I saw a BABY BIG HORN SHEEP climbing up from below to cross the road.

I peered over the edge from which the lamb had just come, and saw that we had split the herd into two -- While there were about 6 up above us, there were about a dozen below us, apparently wanting to follow the rest of the herd to the uphill side of the road (sorry sheep -- we didn't mean to split you up!).

After snapping a few pictures, we noticed that the sheep up on the hill had begun to move again -- And in the process, had sent a boulder about the size of my torso rolling down the hill! Needless to say, we gave up on pictures, hopped back in the truck, and hauled down the windy, mountain road in reverse."
