The "Overpass" from Burgess' LO-III-167-H2,

... and from my LO-III-164-H2

Located adjacent to the large double crater in the center of Fig. 3, this object has the appearance of an overpass or trestle, perhaps once traversing the the shallow depression it overhangs. Clearly reflecting a lot of sunlight, it blots out the rocky terrain below and has a box-like, "stepped" construction ...

version.
Bara version.
The "squaring" of the steps may be due to image compression in the "Burgess version", but it certainly has the appearance of a staircase of some sort. The object is probably about 2-3 stories high, and is not likely to have been caused by debris from the crater formation or volcanic action. It is a "spike" standing up over the edge of the crater where it should not be. Unfortunately, it is not likely this object has been photographed in any other NASA frames, and it is far too small to resolve with Clementine's instruments.
