NASA Mars Rover "Curiosity" finds remnants of an ancient streambed on Martian surface. Curiosity science team member Sanjeev Gupta explains how rounded pebbles spotted by the rover are convincing evidence of an ancient streambed on Mars and William Dietrich explores the relationship between river fans found in California's Death Valley on Earth and similar fans in Gale Crater on Mars.NASA's Curiosity rover found evidence for an ancient, flowing stream on Mars at a few sites, including the rock outcrop pictured here, which the science team has named "Hottah" after Hottah Lake in Canada's Northwest Territories.

Without organic matter building up, without lots of water transporting large amounts of sediment, is it possible that it takes muuuuch longer for sedimentary layers to build up on Mars than it does on earth? And if so, could rounding of that size of pebbles still be explained by wind?

I disagree. I find it so sexually stimulating that I'd like to stick my penis into that bed of pebbles.
