Mountains and passes were important in the formation
of the sand dunes.

You are looking at the Sangre de Cristo Mountains. Prevailing southwesterly winds carrying sand across the San Luis Valley were blocked by the mountains.

As the winds rose to sweep through the passes, sand was dropped.

Some storms come from the northeast and reverse the wind flow through the passes, blowing sand back toward the Dune field.
