|Halfway there at Teakettle Junction. |
Actually one of few places you had cell service.
That's me talking to a colleague back at Ananda Village
The Racetrack Playa, or The Racetrack, is a a scenic dry lake with "sailing stones" that inscribe linear "racetrack" imprints. It is located above the northwestern side of Death Valley.

The playa is exceptionally flat and level with the northern end being only 1.5 inches higher than the southern. This occurrence is due to major influx of fine-grained sediment that accumulates at the north end during wet season and then the clay mud dries out and cracks into a mosaic pattern, easy to walk on when dry.
These sailing stones are a geological phenomenon found in the Racetrack. Slabs of dolomite and syenite ranging from a few hundred grams to hundreds of kilograms inscribe visible tracks as they slide across the playa surface, without human or animal intervention. The tracks have been observed and studied since the early 1900s, yet no one has seen the stones in motion.
The sailing stones are most likely moved by strong winter winds, in the upwards of 90 mph, once it has rained enough to fill the playa with just enough water to make the clay slippery.
Another alternate hypothesis builds upon the first. As rain water accumulates, strong winds blow thin sheets of water quickly over the relatively flat surface of the playa. Sheets of ice form on the surface as night temperatures fall below freezing. Wind then drives these floating ice floes, their aggregate inertia and large area providing the necessary force required to move both small and large stones.
Regardless of how, it is pretty amazing to see.
|Is this? yes it is Oyster shells from an ancient seabed|
|That's me all right. Another long shadow!|
