Blueberries at "Stone Mountain," Opportunity sol 14 When Opportunity examined the soil inside Eagle Crater, the rover spotted strange round pebbles that the rover team referred to as "blueberries" for their relatively blue color (they are actually gray, but that is "bluer" than the red soil) and for the way they appeared dotted around like blueberries in a muffin.
