Stream Bed Found On Mars, Says NASA

The Mars rover Curiosity has turned up something that is indeed curious.  Scientists studying images of "stones cemented into conglomerate rock" have opined that the formation is evidence of a stream flowing at about 3 feet per second.  The estimate of the stream's depth ranges "somewhere between ankle and hip deep", according to Curiosity science co-investigator William Dietrich, of UC Berkeley.  A rock outcrop near the stream bed has been named Hottah, after Hottah Lake in Canada's Northwest Territories.
