Just past the La Sal Mountain Overlook, after entering Arches National Park off Route 191 north of Moab, is a small overlook of the Petrified Sand Dunes that make up a great portion of the park.

Over the past 200 million years, sands blown in from the northwest made this area a huge desert. Over time, the layers of sand were compressed and turned into quartz and the Navajo Sandstone that makes up most of the intricate rock formations in the area.
Erosion has since washed away the covering layers, exposing the petrified dunes.
It was worth stopping at this small overlook.
