The Race Track Playa in Death Valley, California, in the United States of America is a place of strange and unique geological occurrences. Rocks move slowly over the vast lands leaving trails behind. This place has been under scrutiny since 1940. Researchers have recorded the slow movements of rocks and examined their trails.

About Racetrack Playa, California

Racetrack Playa is 3608 feet above sea level. It is 4.5 Km long north to south, 2 Km wide east to west. The surface area is about 7 sq Km. The Racetrack Playa is an endorheic basin with Cottonwood Mountains on the east and the Nelson Range to the west.

The climate in Racetrack Playa is arid with no vegetation. A few inches (3 - 4) of rain falls in a year. When there is heavy rainfall, water from the mountains surrounding the Playa gushes down onto the flatland forming a temporary lake. This water escapes into the cracks and crevices on the flatland, forming a shallow endorheic lake for a short time.

During summertime, the water evaporates, leaving behind cracks and crevices that almost look like hexagons, and some of the water finds its way deep down into the earth.

An endorheic basin allows no outflow of water into the sea or rivers. The water that falls in this area is trapped in cracks and crevices. This water evaporates or seeps deep down into the earth. The endorheic basin is also called an internal drainage system.

The Racetrack is dry around the year. During the dry season, you can see hexagonal shapes of dry cracks on the surface.

The Amazing Geographical Phenomenon – The Sailing Rocks

Racetrack Playa is a place where a strange geological phenomenon occurs from time to time. The rocks in Racetrack Playa move slowly across the flatland leaving behind track marks. These rocks weigh more than 100 pounds.

Smooth rocks leave flat, slippery trails, whereas the rocks with rough edges leave behind striated tracks. The rocks move only once in two to three years. These rocks move in pairs or by themselves. Some trails lead to huge rocks, and some disappear without a trace.

The tracks are about ten to a hundred feet long and 3-12 inches wide. These rocks are either dolomite rocks from the mountains or igneous rocks.

There are a few explanations as to why exactly these rocks move without any human or animal intervention.

1. The moisture between the cracks and crevices make the mud smooth and slippery. This makes it easier for the rocks to move when there are high-speed winds.

2. During the rainy season, the water seeps into the cracks, and crevices are chilled to form long stretches of ice sheets. This, combined with the force of the wind, helps the rocks to move across slowly.

Racetrack Playa is researched and studied by NASA with great interest because it resembles the dried lakes on Saturn’s moon Titan.

The search is still on to find out what exactly is happening to solve the mystery of the moving rocks in Racetrack Playa.

Thank you for taking the time to read and for your lovely comments.

Chitrangada Sharan from New Delhi, India on March 27, 2019:

This is an interesting and informative article about the moving rocks.

I have heard about it from some of my relatives, who have visited this place.

Thanks for sharing the details in this well written article with excellent pictures.

Elias Zanetti yes it is so fascinating and mysterious!

Informative and fascinating hub, Vellur! This is quite an interesting mystery case that I haven't heard before.

Nithya Venkat (author) from Dubai on June 12, 2013:

Cyndi10 thank you and I wish someone would see them move and take a video of it. It would be great!!

Cynthia B Turner from Georgia on June 12, 2013:

Fascinating phenomenon. None of the theories seem to be the answer. I guess you should never use those boulders as landmarks. LOL. Very strange. Funny that no one has ever seen them move. Good hub and videos attached.

Stephanie Henkel thank you and am happy you enjoyed reading. I wish someone could get to see and record the moving rocks!!

Stephanie Henkel from USA on March 04, 2013:

Death Valley has so many interesting and beautiful places, but this one is quite a mystery! I've been to see these moving rocks, but haven't heard all of the theories that you presented on why they've moved. I enjoyed your interesting and informative hub!

Nithya Venkat (author) from Dubai on December 12, 2012:

MartieCoetser thank you, must be interesting out at your place. Sometimes this seems so spooky, specially if we see the second video.

Martie Coetser from South Africa on December 12, 2012:

What an interesting phenomenon! Similar down here, but not due to the same conditions, is roaring sand dunes. Thanks for this interesting hub about the walking rocks in the Death Valley, vellur :)

RTalloni on October 23, 2012:

So interesting to read about these rocks! I drove through the desert years ago and always wondered what it would be like to go back and explore. Imagining all the secrets Death Valley holds is mind-boggling. The first video makes perfect sense. The winds and temperatures there can be savage.

Nithya Venkat (author) from Dubai on October 18, 2012:

I wonder when this mystery will be solved!! This is a real mystery. Thank you for the vote.
