One of the places I visited on my recent trip was Keyhole Canyon, in the desert south of Las Vegas. The sky was overcast so my photos didn't turn out as nice as I wanted. The site is covered in petroglyphs. Most of which are high up on the rocks making it very difficult to reach them. It gets a lot of visitors, being so close to a large city, and some of the petroglyphs have been vandalized.
I got there early in the morning to avoid the heat. It was only 95 degrees. I used the nifty zoom on my new camera to snap pics of the glyphs that were too high to reach. The small canyon ends at the base of a small (25-30 ft) pour-over with a small stagnant puddle of water that had its own swarm of insects hovering over it. At one point, I looked up to see that I was being watched by a couple big horn sheep.
