Please generate a brief description of an unexplored scene outside a sand dune with dunes, pillars, and boulders.

Tall pillars of stacked sandstone joined at the top by narrow beams of dry timber form the Dune Gate, bordering the path as it dwindles to little more than a valley leading westward into the great star-shaped dunes. To the east the sands recede ever so slightly, becoming shallow, manageable hills of earth. Along the side of the trail rest a half-dozen rounded boulders, unmarked and smooth, their purpose not immediately apparent.
