The Racetrack

The last time I went to the Racetrack in Death Valley was 2016. The numerous tire tracks left by people who had driven on the playa when it was wet combined with all the missing stones pilfered by unthinking tourists made me stay away. I thought that maybe with the heavy rains seen in the area the last couple of years may have allowed the playa to recover, so I ventured out.

For those of you who haven't been there, this is Teakettle Junction. People leave teakettles with messages on them. When they get too numerous, the NPS rangers clean it up to leave room for new ones.

After a long, slow, bumpy drive, the Racetrack with the Grandstand on the north end come into view. It reminds me of suiseki, the Japanese viewing stones.

And finally, the sailing stones or magic rocks or whatever other monikers they have.

I was hoping that the sun would come out, as at certain times, it casts a golden glow on the edges of the tracks. Alas, it was not to be. I was happy enough that there were rocks with their tracks.

You came away with some great shots Monika. It's too bad you didn't get some really nice light, but still you found a couple of great rocks with trails. The last one is my favorite with two rocks racing.

I am with Jim - I like the racing rocks :) Glad you got the rocks where the only tracks were from the rocks and not off-roaders.

Yes, that's my favorite one, too. There was another that looked like one (larger) jut ran over another (smaller) one, but I didn't get the optimal angle, or maybe I needed a longer lens to compress them.
 
That was a great visit, Monika. When I was in graduate school, I studied these playa scrapers to try and figure out their mode of movement. I discovered a location that showed that they were definitely blown by the wind and did not need a sheet of ice to enhance their ability to move as one hypothesis suggested. Notice in the image below that the tallest rocks travel farther than the smaller and shorter rocks because they have a bigger surface to catch the wind. Also notice that they all have the same signature as the wind shifts direction.

That's a good illustration of it, Doug. I always enjoy your erudite expositions.

That's so cool Doug! How old is this image?
