Hello Paul H.,

Thanks for pointed criticism and leads.

If you choose, you could start exploring the many hints of major
anomalies re the Gulf of Mexico Holocene geology --

here I add !!! to indicate some candidates:

GEOLOGY
Today, the Gulf of Mexico is a small oceanic basin surrounded by
continental land masses. Due to their physical structure, the Gulf and
the Caribbean Sea are sometimes combined and referred to as the
'American Mediterranean'. Uchupi (1975) divides the Gulf into two
distinct geographical provinces (Terrigenous and Carbonate) while
Antoine (1972) recognizes seven. The scheme proposed by Antoine is
presented here, with additional information derived from other
sources.

1) Gulf of Mexico Basin
This portion of the Gulf of Mexico contains the Sigsbee Deep and can
be further divided into the continental rise, the Sigsbee Abyssal
Plain, and the Mississippi Cone. Located between the Sigsbee
escarpment and the Sigsbee Abyssal Plain, the continental rise is
composed of sediments transported to the area from the north. !!!

The Sigsbee Abyssal Plain is a deep, flat portion of the Gulf bottom
located northwest of Campeche Bank. In this relatively uniform area of
the Gulf bottom, the Sigsbee Knolls and other small diapiric (salt)
domes represent the only major topographical features. The Mississippi
Cone is composed of soft sediment and extends southeast from the
Mississippi Trough, eventually merging with other sediments of the
central basin. The cone is bordered by the DeSoto Canyon to the east
and the Mississippi Trough to the west, and has been described in
detail by Ewing et al. (1958).

2) Northeast Gulf of Mexico
Extending from just east of the Mississippi Delta near Biloxi to the
eastern side of Apalachee Bay, this region of the Gulf bottom is
characterized by soft sediments. To the west of the DeSoto Canyon,
terrigenous (land-derived) sediments are thick and fill the remnants
of the Gulf basin. !!!

In the eastern portion of the region, Mississippi-derived sediments
cover the western edge of the Florida Carbonate Platform and a
transition towards carbonate sediments begins. The Florida Escarpment
separates the Florida Platform from the Gulf Basin and also forms the
southeastern side of the DeSoto Canyon. In a region characterized by
sediment deposition, the presence of the DeSoto Canyon is poorly
understood. !!!

Some theories suggest that the canyon is the result of erosion caused
by oceanic currents, possibly the Loop Current (Nowlin, 1971).

3) South Florida Continental Shelf and Slope
A submerged portion of the larger emergent Florida Peninsula, this
region of the Gulf of Mexico extends along the coast from Apalachee
Bay to the Straits of Florida and includes the Florida Keys and Dry
Tortugas. A generalized progression towards carbonate sediments occurs
from north to south ending in the thick carbonate sediments of the
Florida Basin. Evidence suggests that this basin was at one time
enclosed by a barrier reef system (Ewing et al., 1966; Sheridan et
al., 1966; Oglesby et al., 1965; Antoine and Ewing, 1963). In the
Straits of Florida the Jordan Knoll appears to be composed of remnants
from this ancient reef system. Evidence suggests that this reef may
have once extended across the straits, adjoining the Florida reefs
with those of northern Cuba. !!!

4) Campeche Bank
Campeche Bank is an extensive carbonate bank located to the north of
the Yucatan Peninsula (Ordonez, 1936). The bank extends from the
Yucatan Straits in the east to the Tabasco-Campeche Basin in the west
and includes Arrecife Alacran. The region shows many similarities to
the south Florida platform and some evidence suggests that the two
ancient reef systems may have been continuous (Antoine and Ewing,
1963; Uchupi and Emery, 1968). Continental drift and erosional
processes are both theorized to have played a role in the separation
of the two geologically similar carbonate platforms. !!!

5) Bay of Campeche
The Bay of Campeche is an isthmian embayment extending from the
western edge of Campeche Bank to the offshore regions just east of
Veracruz (~96 degrees W). The Sierra Madre Oriental forms the
south-southwestern border, and the associated coastal plain is similar
to the Texas-Louisiana coast in the northern Gulf. The bottom
topography is characterized by long ridges parallel to the exterior of
the basin. Salt domes are prevalent in the region, and the upward
migration of salt is theorized to be a cause of the complex bottom
profiles (Worzel et al., 1968).

Similar to the northern Gulf, large quantities of oil are produced
here, and thick terrigenous sediments predominate. !!!

6) Eastern Mexico Continental Shelf and Slope
Located between Veracruz to the south and the Rio Grande to the north,
this geological province spans the entire eastern shore of Mexico. The
Gulf bottom of the region is characterized by sediment-covered folds
that parallel the shore. Apparently created by sediment-covered
evaporites, evidence suggests that the folds have impeded sediment
transport from the Mexican coast to the Gulf Basin (Bryant et al.,
1968). As sediment cover increases from south to north, so does the
relative complexity of the bottom structure. !!!

7) Northern Gulf of Mexico
The northern Gulf of Mexico extends from Alabama to the U.S.-Mexico
border. North to south, the province extends from 200 miles inland of
the present day shoreline to the Sigsbee escarpment. Sediments in the
region are generally thick with the greatest sediment load provided by
the Mississippi River. Widespread salt deposits are present throughout
the region (Murray, 1961; Halbouty, 1967) and these structures act to
create subsurface and emergent topographic features on the continental
slope such as the Flower Garden Banks off the Texas/Louisiana coast,
and the pinnacles region offshore of the Mississippi/Alabama coast.

http://en.wikipedia.org/wiki/Gulf_of_Mexico

In 2002 geologist Michael Stanton published a speculative essay
suggesting an impact origin for the Gulf of Mexico at the close of the
Permian, which could have caused the Permian?Triassic extinction
event.[13]
However, Gulf Coast geologists do not regard this hypothesis as having
any credibility.
Instead they overwhelmingly accept plate tectonics, not an asteroid
impact, as having created the Gulf of Mexico as illustrated by papers
authored by Kevin Mickus and others.[7][10][14]
This hypothesis is not to be confused with the Chicxulub Crater, a
large impact crater on the coast of the Gulf of Mexico on the Yucatan
Peninsula.

Dear Rich,

You need to do your homework before you get carried away
with interpreting what you see on Google Earth. The geology
of the "Gulf of Mexico from S Texas to W Florida" is known
in extreme details from decades of research by academic and
oil company geologists and from thousands of kilometers of
seismic data, thousands of piston cores, innumerable
geotechnical borings, and data from innumerable oils and
gas wells. There is more than enough data and research,
both published and unpublished, to totally refute the below
interpretations and show that the ideas about "continental
flood debris edge 1 km thick" underlying the Gulf of Mexico
is total fantasy. The ?oil well cores? and other data show
that the ?massive dump of mud, sand, broken rocks, and
km scale pieces of rock wafted right off the lands of North
America -- 1 km thick,? which you talk about below exists
only in your imagination.

I just looked up some specific underwater landscape SE of
Corpus Christi:

[ Dennis Cox, who has taught me how to look at many landscapes
with new eyes, has an eighth grade education, and has been a
welding inspector in Fresno, California.

2108 m deep high point, 909 m above level plain to N at
2999 m deep -- this is where the debris flood surge came to a
stop, leaving a very similar edge all the way from south Texas
to west Florida -- it'd be interesting to show what oil well cores
show about this massive dump of mud, sand, broken rocks,
and km scale pieces of rock wafted right off the lands of North
America -- 1 km thick.
