Curiosity is now back at the intriguing Shaler rock outcrop, after having initially passed it during its first trip into Yellowknife Bay in Gale crater. Shaler consists largely of “stepped” flat rock slabs which stand out from the surrounding rocks and soil. It’s origin isn’t known yet, but may be connected to the fact that this area was once very wet, with flowing streams and possibly a lake, according to findings so far by the rover. Curiosity’s findings here should be interesting, and then the journey begins to the layered foothills, buttes and mesas of Mount Sharp!
