I think this is a great example why more specific tags are advisable to use in 
OSM than a generic bare ground tag.

What this picture shows is commonly known as desert pavement:

Apart from varying in size distribution and density as well as material of the 
stones these form a fairly characteristic surface that can and should be mapped 
distinctly.  As size of the larger stones strongly affects navigability, 
specifying that would be a valuable supplemental tag.
