watch this thread daily. New Orleans, here, and interestingly, this is still the best info out threre in regards to our sinkhole. Thanks to everyone
for providing so much information
having said that, just wanted to shoot something CB's way, nodding to his good info and participation here. Do you remember a few stories on local
news (WDSU) a few months back about a "salt wedge" traveling up the MS river, and causing some problems with those getting their water supply from
the river? The "fix" was building up a sand or silt bar to slow it down and provide some filtration, I believe, if I remember correctly.
I mention this, obviously, because it was interesting it was salt. And also, when one drives over the area on I-10W
and 55N before and after the Bonne Carre Spillway, there are oodles of dying cypress trees, which we were told over the years died because of salt
water incursion, due to the construction of the spillway and the army corps of engineers solutions to flooding. Of course, there are probably many on
this thread that may not realize what a huge issue this is here in Southern Louisiana, and particularly since Katrina. New Orleans is a former swamp,
after all, surrounded still by water, between the river and Lake Pontchartrain, with a system of levees and the spillway, nodding here also to the
Morganza Spillway, as well as the Bonne Carre, all of which "push" that water back to make dry land and the cities possible.
The "salt ridge" on the river really peaked my interest. It's been an issue, I believe, the last two Augusts. Then we have this sinkhole, and it
happens to be related to the seeming liquefaction of a salt dome. Water moving through salt easily dissolves and dislodges, and then the salt will
show up other places, logically.
Another thing I would like to bring up just for some of the better minds present to think about is that it was suggested at the time that the Macondo
well had drilled into a batholyth. If one researches the analysis of the geological formation called a batholyth, the salt domes would be a feature
of a particular level, geologically of the said batholith. If those of you interested, research this particular formation, I think you will find
interesting implications in regards to everything discussed in this thread.
Again, thanks for informing me as to all the happenings.
