Here we are in Fallon, MOH and I, getting ready to cross the desert to the east. I'm in the Prius, he's on the motorcycle, taking it out to our little house in eastern Nevada. We'll now have two high-mileage vehicles to drive, except when I take my 4WD to work
As we approach Sand Mountain - shown as "Sand dunes" north of Highway 50 on the above topo map - the blowing sand has completely enveloped what is often a large RV city on the east flank of the dune (right side of the photo).
The Salt Wells Basin is undergoing a bit of a dust storm, with dust blowing off the mostly dry playas across the road, this time from the south. Deflation is a term often used for this kind of wind erosion, when wind removes the loose, fine-grained material - in this case the dust and fine sand of the playa - and carries it away, directly into our path!
And then we pass straight into the path of the dust and fine sand as it crosses the road just before the turnoff to Sand Mountain.
Ah, but the trip isn't over: we've now gone over Sand Springs Pass, and will cross LaBou Flat in Fairview Valley. Thermal updrafts below the overhead cumulus clouds are drawing dust off the valley floor, but not causing the rotation that creates true dust devils.
The above three photos show the dust in Fairview Valley, the first two looking to the east, the third looking southward from about the center of the valley, near the old site of Frenchman.
Finally, we have crossed Fairview Valley, have crossed Stingaree Valley, and are entering the notch in the western part of the Clan Alpine Mountains, which is called West Gate.
As we arrive at Middlegate Junction - an old stage station between West Gate and Middlegate, the first two of three geographic notches that old Highway 50 passes through - we see that dust is still blowing. [The current path of Highway 50 makes it through only West Gate and Middlegate, missing Eastgate by a short few miles.]
