Free highres HDR map from a desert scene

A good collection of HDR images can make the difference for an architectural visualization artist, and if you use Blender Cycles a lot I must say that an HDR map can really make the quality of your projects to change. This is why I`m always looking for new HDR maps and with more options I can decide which ones will fit better for a particular project.

Here is another highres HDR map from a desert scene available for free on Turbosquid. The size and quality of this HDR map is amazing, considering that the author is offering this for free.
