GPS Helps Solve Mystery of Sliding Rocks

August 28, 2014By
Rarely formed sheets of ice push rocks across a dry lake in Death Valley.

In Racetrack Playa in Death Valley, California, hundreds of rocks — some weighing as much as 700 pounds — seem to have been dragged across the ground, leaving synchronized trails that can stretch for hundreds of meters. Though many phenomena were speculated (hurricane-force winds, dust devils, slick algal films, thick sheets of ice), no one knew what caused the movement. To solve the mystery,... read more

A network of GPS stations in the western United States is revealing the severity of the drought in that region. Compared to the nine years before the drought, the GPS data show that the western United States has lost 240 gigatons of water, which is enough to flood the entire region in 10 centimeters of water. Investigating ground positioning data from... read more
