Surf's up! Well, not exactly. Rock and sand formations that are shaped like waves are a wonder on this Earth, but they surprisingly don't have much to do with the ocean. In fact, they'll require your ...

Researchers have analyzed an extensive collection of sand samples from so-called megaripple fields around the world and gained new insights into the composition of these sand waves. These could help ...

Amid the state’s record-low snowpack, however, it seems likely that Medano Creek will not flow as it usually does this year.

THE sand waves dealt with in this paper are not the well-known “current mark,” or ripple mark of rivers, but the larger sort, first scientifically described by Prof. Osborne Reynolds. These larger ...

Getting your Trinity Audio player ready... Surf’s up in Medano Creek at Colorado’s Great Sand Dunes, sort of, thanks to bountiful snow in the high peaks above the dunes. OK, you can’t really surf ...

Waves of sand on the parched surface of Mars, spotted by NASA's Curiosity rover, are reminiscent of ripples on the surface of a lake. While there may have once been lakes, rivers and oceans on the ...

San Francisco long has been renowned for its hills, bay and bridges -- but not for expanses of sand dunes. That's liable to change. It turns out there are more than 2 square miles of dunes right next ...

Desert snakes slithering across the sand at night can encounter obstacles such as plants or twigs that alter the direction of their travel. While studying that motion to learn how limbless animals ...
