Geology LITE: Rocks On The Go… Vroom Vroom!!

We all know the earth moves, but these rocks defy logic.

The rocks of Racetrack Playa.

These rocks have legs.

They’ve got some get up and go.

How exactly do they get around?

Here’s the low down:

Racetrack Playa is located in Death Valley National Park in California. The Playa is an extremely flat lakebed that is usually dry. The sediment at the surface of this dry lake bed is uniformly fine… silt and clay sized particles. Following an infrequent rain, when these fine sediments get wet, they become very slick. As the rain evaporates and infiltrates… and when a big wind blows in… the rocks go vroom vroom.

Burn rubber!

Rocks on the go… vroom vroom!!

Have you ever seen rocks on the go… landslide, earthquake, Racetrack Playa?

    Personally, I believe the aliens come down and play a giant board game with these huge boulders when we’re not looking.

    I would so love to see this happen. But since nobody can seem to catch it happening on film either, I’ll probably have to wait and watch it from my seat in heaven.

    Loved seeing more about this today, Chris!

    Is this like brown sugar when you scoop it up and it actually moves like it’s a living creature? I get a kick out of that each time I use brown sugar and just watch it creep.

      Oh my goodness… I think that creepy brown sugar thing is a living food phenomena analogy! Kudos Chris!!
