re: Cool picture!
I could do the maths with the stereo pair....

Range approx 29.6m (+/-0.4m)
Height, about 50cm - from the bottom of the top part of the overhang, to the small rocks below.
From the peak of the top of the outcrop to the rocks on the ground below, about 75cm
To give you an idea - the Barnicle Bill look-a-like bottom right of frame is 9.4m away, 23cm wide, and 11cm tall
Another few Navcam frames have just dropped into the Exploratorium...
