The view shows the small pit a38 after the fill f448 was removed. Somewhat visible is the curvature of f447 which originally suggested to us that it might be a pit cut. v271a looks at the surface of f423 behind a38, which is smooth and striated, like f450, rather than rough, as f423 has been. v471b is a view of f450 above a38 for comparison. The only explanation that seems to make sense for the face of f423 here is that an air pocket opened up in this part of the fissure, creating conditions in which the smooth face could form on top of the mud ledge layers. Either that or, unlike anywhere else in the circle, the smooth face built up in layers here, joining the mud ledge. This can also be compared with v272. |
