Death Valley's sliding rocks may actually hitch a ride on ice rafts

The sliding rocks of Racetrack Playa in Death Valley, California have mystified and delighted visitors for decades (previously). Now planetary scientist Ralph Lorenz and colleagues think they've figured out how the rocks get around: ice rafts float the rocks out of the mud, reducing friction enough that modest winds can push them along (PDF of Lorenz et al., American Journal of Physics, Vol. 79, 1 January 2011).

Expeditions to the Polar Regions

The Polar Discovery team has documented science in action from pole to pole during the historic 2007-2009 International Polar Year, and covered five scientific expeditions. The science projects explored a range of topics from climate change and glaciers, to Earth’s geology, biology, ocean chemistry, circulation, and technology at the icy ends of the earth. Through photo essays and other multimedia, they explain how scientists collected data and what they discovered about the rapidly changing polar regions. From the awesome folks at WHOI.

Next Thursday, NASA will announce the discovery of huge water ice oceans on Mars. Lying less than a metre beneath the surface south of 60° latitude, the water ice reservoirs if melted would form an ocean 500m deep covering the entire planet. NASA insiders believe these findings could result in a manned landing within 20 years.
