The rocks in Death Valley move across the Racetrack Playa surface in a mysterious manner, leaving trails behind them. It is believed that a combination of wind and thin sheets of ice allows the rocks to slide across the playa, leaving behind their distinctive trails in the mud.
First of all, why would rocks move in different directions? Even though rocks could move in different directions, it is not possible for them to move on their own. Rocks have to have force applied to them in order to move.
Strike slip fault
When rocks on opposite sides of a fault move in opposite directions, it is called a strike-slip fault. When they move in the same direction, it is called a normal or reverse fault, depending on the type of stress causing the movement. The rate of movement can vary from slow creep to sudden jolts during an earthquake.
Rocks that move in opposite horizontal directions are called strike-slip faults. In these faults, two blocks of rocks slide past each other horizontally along a fault plane in opposite directions. This movement is caused by shear stress in the Earth's crust.
This process of rocks moving in opposite directions on opposite sides of a fault is known as strike-slip faulting. The movement can be either left-lateral (sinistral) or right-lateral (dextral), depending on the relative lateral displacement of the blocks. If the rocks move in the same direction but at different rates, it may indicate differential movement caused by friction variations along the fault plane.

The Racetrack is always there, how often the rocks move cannot be determined as no one has witnessed them move in over 100 years.
A continental glacier can move in all directions and a valley glacier can move in a surge. :)
