Racetrack Playa , a mostly dry lake off the beaten track in Death Valley.
About the "migration" of stones there are some different explanations. However, so far no one has been able to observe.
After all, the phenomenon of the wandering stones does not seem to be so rare. In California alone, it should give them to 16 points.

Racetrack Playa, ein meist ausgetrockneter See abseits der üblichen Routen im Death Valley.
Über die "Wanderung" der Steine gibt es einige, verschiedene Erklärungsversuche. Bislang hat es jedoch noch niemand beobachten können.
Immerhin scheint das Phänomen der wandernden Steine nicht so selten zu sein. Allein in Kalifornien soll es sie an 16 Stellen geben.

I hope everyone is having a great weekend!
Edit: as I understand it, these rocks slide across the desert floor during or after rainstorms when the ground is soft and wet. Extremely high winds and gravity create this phenomenon.
The southern end of the Racetrack still had water from December storms, but I don't know if conditions were right for the rocks to sail.
Hope you have a good start to the weekend. Thanks for stopping by and for all of your kind comments, awards and faves -- I appreciate them all.

After a cold night in a tent at the campground the sun was very welcome to our frozen selves!
Racetrack, Death Valley National Park
Looking south from the Grandstand area of The Racetrack.
The Racetrack is a dry lakebed formed roughly 10,000 years ago when the climate changed from wet/dry periods to mostly dry. The fine sediment is the result of erosion from the Cottonwood Mountains on the east and the Nelson Range to the west. The accumulated playa is approximately 1,000' thick, running north to south. The grade change is only about 1.5 inches higher at the north end of the playa than the southern end, a distance of roughly 3 miles. The width of the Racetrack varies from 1.75 to 2 miles wide.
The Racetrack Playa, or The Racetrack, is a scenic dry lake feature with "sailing stones" that inscribe linear "racetrack" imprints. Nestled in a remote valley between the Cottonwood and Last Chance Ranges, the Racetrack is a place of stunning beauty and mystery. The Racetrack is a playa--a dry lakebed--best known for its strange moving rocks. The Racetrack is a playa (dry lakebed) about 3 miles long and 2 miles wide. At least 10,000 years ago this region underwent climatic changes resulting in cycles of hot, cold and wet periods. As the climate changed, the lake evaporated and left behind beige colored mud, at least 1,000 feet thick.

The moving rocks in this remote area were a mystery until 2013 when scientific monitoring of the rocks discovered how they moved across the playa leaving a distinct trail. With sufficient rain, the southern end of the playa becomes a shallow lake. In winter, the surface of the lake freezes into a floating sheet of ice enclosing the rocks. When the ice sheets break apart, a steady strong wind catches the floating ice sheets pushing them along with the embedded rocks leaving their marks in the soft playa. The rocks are now at a new location until the next similar event which may take several more years.
Another E9 doubleheader, this time still working on the BN, and in passenger service as EMD intended. We have the 9924 and 9906 rounding the curve at Lisle IL with westbound train 1247 on 28 June 1989. Typically two trains a day operated with tandem units, to rotate protect power at Aurora.
When we first arrived at the Racetrack Playa there were a few groups of people enjoying the playa flying kites and taking pictures. I suspect they were thrilled about having survived 26 miles of bone shaking on the Racetrack Road and gathering courage for the return trip!
Day five I took a suburban the entire length of the Racetrack to Chicaaaaahgo...
Gotta love front facing windows. Gotta love gallery cars. We love the BN, don't we folks?
It's a snowy New Year's Day evening as pair of CN SD75Is on symbol M337 pull out of Hawthorne Yard for headroom, at Lavergne where the Freeport Sub crosses above BNSF's Chicago Sub "Racetrack".
Most likely the trail left by the larvae of an Aspen Leaf Miner Moth (Phyllocnistis populiella)

Passenger and freight race each other into Clarendon Hills, IL during the morning commuter rush on Burlington Northern's "racetrack".
Death Valley National Park
Dry lake, sometimes filled with water, is located in the north-western part of Death Valley National Park, California, USA. Is known an interesting geological phenomenon - moving along the dry bottom of the stones.
This was another take on the crazy wild trip to the Racetrack with my homeboys Jave and
James. We all came back with some nice images on this night, check out Jave's image and then when you get done picking your jaw off the floor, check out Jame's shot. You'll probably need to slap your self a couple times, once you get done looking at these images. Talking about sensory overload!
Tardiness has become more the norm than the exception for FEC train 109 lately, with this one pulling into Hialeah Yard late on a Thursday afternoon. To put the icing on the cake, the three EMD lashup whereas EMD power occasionally seeps into the 109-210 pair. The overpass in the background is a walkway from the Metrorail station to the Hialeah Racetrack, a signature radio location on the FEC channels. "Racetrack single track in" is a common call over the radio for trains like this. To the left of frame, the east leg of the old wye that spun dedicated passenger trains going to the track. It served Gilda and two lumber customers until the last decade where it now sits rusted awaiting its fate.
The Racetrack, also known as the Racetrack Playa is a scenic dry lake feature with "sailing stones" that inscribe linear "racetrack" imprints. The Grandstand is to the left.
During periods of heavy rain, water washes down from the Racetrack mountain area, drains into the playa, forms a shallow, short-lived endorheic lake. Under the hot desert sun, the thin veneer of water quickly evaporates leaving behind a surface layer of soft slick mud. As the mud dries, it shrinks and cracks into a mosaic pattern of interlocking polygons.
The mystery of the "sailing stones" will be revealed in my next post.
Happy Wednesday! Thanks for stopping by and for all of your kind comments, awards and faves -- I appreciate them all.
