The Mysterious Sliding Rocks- By: Michael W.

In Death Valley national Park there are huge rocks with mysterious trails behind them.  The truth is that nobody really knows how they move but people have come up with many theories.  One theory is that people or animals moved it but this is impossible because it is believed that it was moved during a very muddy time and there are no human or animal footprints near it.  Another theory is that it was maved by ice.  People have seen times where Racetrack Playa was covered by a sheet of ice.  While it was covered they say wind moved the rocks.  This theory is wrong too because they haven’t  found any evidence of the ice’s effect on the landscape and tests have shown that it is impossible.  The most favored theory of them all is wind moving the rocks.  Wind has been used in every method and theory developed, therefore it most favored and most likely right.

Discussion Questions:

  1. Do you have a theory of  how the rocks moved?  What is it?
  2. Which of the theories above do you think is the best?  Why?

  1. I think that people moved. I do not think it is possible for any other reason. i think this this is the best thoeory because the other do not make sense

  2. Great Job Michael!!! I don’t have a theory because it seems very odd. The theory that I think is most likely is that it was maved by a big sheet of ice. The sheet of ice could have been really heavy and push the rock when it was falling. THis article was very well written!

  3. I do have a theory of how the rocks moved. It is that the rocks are magnetic. Underneath Earth’s surface, right in the location of the magnetic rocks, are more magnetic rocks that moved underneath the surface somehow, dragging the rocks on the surface with them. I know it’s not the greatest theory and it has some flaws, but it’s all I can come up with. The theory that I think is the best is that the winds moved the rocks because that is highly possible if happening over time. I would’ve said that the ice moved the rocks while the rocks were laying on a sheet of ice because objects slide more on ice, but the tests say that there is no record of any ice having been there.
