Rock 365 : Day 44 : Gabbro Dreikanter #365photos

20100213

Day 44 : Dreikanter is German for “three sides”. This gabbro
ventifact is a classic dreikanter, sculpted by wind blown sand to
produce a three-sided pyramid shape. I brought this sample which is
about 25cm across back from the Atacama Desert of Chile.
