There is a small but significant horizontal component to gravity’s force, similar to tidal forces.

hey Brian Dunning from Skeptoid.com has a great short podcast about these stones…he shows pretty solidly that it is the ice flows that move around the rocks.

I recently visited the racetrack, and I was horrified to discover that a huge number of these wonderful rocks had been stolen and moved. Especially near the parking area, you can see tracks with no rocks, and tracks with rocks which don’t fit, or a rock on each end.

It is evident where the rocks fell from-a loose hillside on the south end (L side of the picture), as all the tracks lead from there. I personally believe wind moves them. The wind was pretty stiff when I was there, though calm elsewhere. The nature of the rock gives the fallen pieces flat, squared sides which provide a)a flat surface to slide on and b)a good surface area to function as a ‘sail’

Agreed Mark… my first instinct was vibrations in the earth. Not big enough to be shockingly noticeable, but enough to move stones bit by bit.

You’ll put an eye out if you’re not careful!

Yeah, har har har.

It is all fun and jokes until you get run over by one of these. Try explaining THAT to your insurance company! “I was just sleeping in my tent and this rock slid into me!” “You mean it ‘rolled’ into you.” “No, it SLID into me! As in ‘sliding’ in the past tense.” “Sure- NEXT!”

Has anyone looked for a hatch anywhere close by?

I blame CERN.

Magnetism will move the rocks. There could be strong magnetic fields under the mud. Or the vibrations from micro-quakes (much more prevelant further down the Colorodo) could move the rocks.
