Unexplained Moving Rocks!

This is an old mystery cant understand why someone does not set up a time lapse camera and put this thing to bed......as for the mud and wind thing those elements are not specific to this area surley rocks all over the world in similar conditions would move also and this is not the case ......the accustics may play a part as that previous post about tibet and the so called musical techniques monks use to lift heavy rocks, a dr.jarl wrote and supposedly filmed the process
