BTNEP and the bayou
Aug. 20th, 2007 02:11 pmIn Louisiana, the Barataria-Terrebonne estuary fills the lopsided delta between the Mississippi and the Atchafalaya. Bayou Lafourche, running down the middle, used to be a major branch of the Mississippi (Lafourche means "the fork"), but it was dammed in 1905 to protect settlers from floods. The dam stopped the flooding, but it also stopped the new layers of sediment that came with the floods, and ever since then the sediment that remains has been compacting, settling, and washing away. (Researchers call this "subsidence".) Today, an acre of land disappears beneath the water every 45 minutes. Hurricanes like Katrina and Rita scour away more sediment, and subsidence makes the hurricanes worse by turning wind-breaking woods and barrier islands into open water, which makes for a feedback loop. Louisiana Highway 1, which used to pass between endless orange groves, now has water lapping at its edges. Telephone poles and gravestones sprout from the sea.

I'll post a day-by-day blow-by-blow shortly. That was the intro.
(The pretty blue Mrs. Crab in the picture was pissed at me for getting between her and the water. She ran back and forth at my feet in the surf, clacking her claws together in the crab version of a rude hand gesture. I got a movie.)
