Dusty devils

We see dust devils all over the Deming, NM area.  Big ones. They are common in the southwest desert where it’s hot, flat and barren and the sky is clear -- and that’s Deming.  And where there is one dust devil, there are often two or three. They can last for minutes.

A dust devil about 20 miles north of Deming, NM 
just off of  Highway 180.  The main cause of a dust devil 
is the difference in the near-surface temperature (hot) 
and the air higher up (cool).
