Bedrock Outcrops in Kaiser Crater

This enhanced-color image shows a patch of well-exposed bedrock on the floor of Kaiser Crater .

The wind has stripped off the overlying soil, and created grooves and scallops in the bedrock. The narrow linear ridges are fractures that have been indurated, probably by precipitation of cementing minerals from groundwater flow. The rippled dark blue patches consist of sand.
