Yes, I have actually shown Joe many Grand Canyon pictographs that I have found. Unfortunately they all require at least a three day off trail backpack trip, which always includes a 1600 foot decent down to the esplanade. Joe's response is always the same " can't we hire a helicopter".
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.
