Tracking Painted Pebbles in the Mojave



To place model rates generated from cosmogenic nuclide analysis of samples from desert piedmonts, we needed short-term measures of sediment movement. To make these measurements, we deployed 1600 painted and numbered pebbles at four sites where cosmogenic nuclide measurements had been used to calculate sediment virtual velocities. The pebbles clearly demonstrated the episodic nature of sediment transport in this arid region.
