Interesting - I have not thought of converting Painted Hills to B&W before. The first two look like the boardwalk path up at the north end of the main road. The B&W and the light angles play really well together with this surface. I like the approach you took for the last image by cropping out the horizon and leaving the focus just down on the painted topography.
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.
