You had some really nice conditions for your visit to these dunes. Only one set of visible tracks just below the dune crest in the upper right leading up to what looks like a person standing atop the dune. Nice contrasts.
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.
