- 08:04, 17 April 2020 diff hist +685 N File:ESP 042625 1655tars.jpg Transverse aeolian ridges (TAR's) Transverse aeolian ridges—or TAR—are mysterious, wind-blown features that are intermediate in size between ripples and much larger sand dunes. Ripples form from hopping sand grains, and dunes form from sand grains being blown over longer distances. One hypothesis for TAR formation is that larger grains like pebbles are rolled on top of smaller ripples; then, finer dust settles into the cracks, “inflating” the pebbles, making the TAR larger than typical rip... current

These images show sublimation of ice in the trench informally called "Dodo-Goldilocks" over the course of four days. In the lower left corner of the left image, a group of lumps is visible. In the right image, the lumps have disappeared, similar to the process of evaporation. Date June 15 and June 19, 2008 Source http://ww... current
