The Gulf of Mexico is probably one of the most extensively studied landform in the Western hemisphere. Driven by the significant petrochemical reserves located here, much science has been done to re-create it's geomorphic evolution. There seems to be little question about the Gulf, so our proposed alternate solution is poorly corroborated.
There are indication of concern regarding the current understanding of its evolution. New Orleans independent geologist Jack M. Reed has raised some points:
"For all the years I have worked the Gulf of Mexico Basin I have been forced to accept the 'passive' Gulf formation theory, which holds that the only movement in the basin is updip sedimentary loading that moved the salt southward," Reed said. "But there is little evidence to support this theory, and it doesn't fit what is observed geologically or geophysically."As Hugh Wilson said (1993), 'It would be geologically unusual for such a large basin as the Gulf of Mexico to remain almost tectonically undisturbed for 170 million years while major orogenic disturbances repeatedly struck bordering areas.'"

The Gulf of Mexico may well be the manifestation of three different PZ Terminal fan Crater events. We present these out of context of a series to demonstrate the process by which the simple geometric structures created by PZ events can be overlain to create more complex structures. The coexistence of these craters in the same location allow for a relative timing assessment to be made. Let us look at the three proposed craters.
The three fan craters are available
using the Google Earth facility by downloading this
Keyhole file.
We have identified the three craters as Pink, Yellow, and White for their colors. We interpret the sequence as having Y last. This is derived from the fact that the ejecta deposits comprising Lake Pontchartrain arrived from the SW, which suggests Y was later than P, and the strike point of Y interrupts the terminal wall of W, so Y must have occurred after W. Terminal fan craters are used in the treatise as the identifier for a given comet interface sequence. The proof sets for Gulf of Mexico Pink (GMP), Gulf of Mexico White (GMW) and Gulf of Mexico Yellow(GMY) are linked to each of these three graphics, below.
The the present time, only the GMY event has been correlated with significant data, as discussed in the GMY Series proof, accessed from the menu on the left, pr by clicking on the GMY graphic below.

Assembled together, they effectively excavate the Gulf. Clicking on this graphic will open a larger version.
We note that the azimuths for outbound ejecta from craters P and Y are well correlated with the two separate emplacement events seen at the Cahokia Mounds site in Collinsville, IL. The sequence of P-preceding-Y is also therefor correlated. A Perigee: Zero discussion of Cahokia Mounds is available in the Enigmas section of this site.
