One thing to keep in mind if thinking it should be easy to find this guy: The desert is big, looks a lot alike, and is more dynamic than people give it credit for. Earthquakes, floods, and other natural things can alter the landscape in subtle ways. Many high yield prospects were lost when prospectors could never find them again for such reasons, leading to many legends of "lost" mines. I also think it's most likely that the man didn't want to be found, sadly. He wouldn't be the first.
