Plates 3 and 4 originally included well MW-13 projected onto section for geophysical correlation purposes. Units intersecting MW-13 on this section were not consistent with units intersecting MW-13 on A-A' and Ad-Ad' (plates 1 and 2, respectively). MW-13 was removed from plates 3 and 4 and units were redrawn at that location.

On plates 8 and 17, two additional units were added to the top of well MW-18. Units intercepted by well E-3 were redrawn to be consistent with units intercepted by E-3 on sections A-A' (plate 1), Ad-Ad' (plate 2), and E-E' (plate 7). Lower unit intercepted by MW-18 was redrawn to be consistent with this change.

On plate 9, the lowermost unit intercepted by well MW-6 was redrawn to be consistent with units intercepted by MW-6 on C-C' (plate 5).

On plates 13 and 14, units were redrawn to be consistent with plates 3, 4, and 5.
