The rock there is a type of granite and I thoroughly enjoyed climbing around on the rock faces photographing the rock art.
Me, climbing up to get a photo of some Petroglyphs.
The rock is a type of granite called Quartz Monzonite.
Desert Bighorn Sheep were always a popular subject for Petroglyphs.
This reminds me of a Jelly Fish!
This was one of the highest from the desert floor.
The turtle in this photo is interesting. The Desert Tortoise was a
food source for the Anasazi and Paiute Indians.
This petroglyph of a Lizard is my favorite!
There were also some Pictographs.
Here is a website that talks about possible explanations about the rock art in Keyhole Canyon.
