The beautiful patterns in the sand dunes are broken by the footsteps of those passing through. The sandstorm on the horizon will make sure that they are wiped clean.
The moon was still high in the sky even after the sun lit up the sky. You look the opposite direction and you see a completely different scene with the burning sun.
It's interesting how the patterns in the sand is accentuated by the side lighting making it seem like a pool of sand nested between the dunes
