Opportunity's Sol 89 PanCam Images
Take a look at Opportunity's PanCam images from sol 89. You have to look at the full-size image to really see what I mean. If you look at the opposite wall of Endurance Crater, you can clearly see some exposed rock. But I can't tell how steep the opposite wall is. Also, there appears to be at least two outcrops of rock around the rim of the crater. Am I seeing things?
