As I was leaving Grand Mesa in Colorado and the road had descended I came across this area and had to stop and shoot as it reminded me of some of Dougs photography.
Very nice, Jim. Thanks for looking for a geological outcrop. This one is really pretty. It looks like there are sandstone layers between some of the shale units. The sandstone is highly jointed which provides the shape for the boulders as Ben suggested.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
