[Texascavers] tawny crazy ants
Crazy ants have been in the press off and on for over 15 years and haven't driven us crazy yet. Maybe these tawny crazy ants are significantly different, but maybe not. The info on the other crazy ant on the AM site is very similar. Anyway, thanks, George, for pointing us to the Texas AM site, which appears to be authoritative. A press release quoting only a guy who runs an exterminating company (and who named the ants after himself) is hardly worth notice. Anyway, sounds like another species that is, with human help, finding a nice new niche. Who says humans only harm species? -- Mixon A little sincerity is a dangerous thing, and a great deal of it is absolutely fatal.

Yes, Bill, tawny crazy ants are different and we only have ourselves to blame for their presence in Texas.

RE: [Texascavers] Holy crap! Sinkhole swallowing trees in Louisiana!
Actually, they used water to bring up the salt and created a big undeground void. The overburden got too heavy and it started collapsing last year. They've been watching it ever since.

RE: [Texascavers] Salt Dome drains Lake Peigneur, LA 1980
Regardless of how it happened, it makes for spectacular video. Date: Thu, 22 Aug 2013 15:32:14 -0500 From: lmcn...@austin.rr.com To: texascavers@texascavers.com Subject: [Texascavers] Salt Dome drains Lake Peigneur, LA 1980 The most dramatic collapse of a salt dome--due to human error--occured at Lake Peigneur LA on Nov 20, 1980. Incredible film/video footage. http://www.youtube.com/watch?v=ddlrGkeOzsI (snip from Wikipedia) On November 20, 1980, when the disaster took place, the Diamond Crystal Salt Company operated the Jefferson Island salt mine under the lake, while a Texaco oil rig drilled down from the surface of the lake searching for petroleum. Due to a miscalculation, the 14-inch (36 cm) drill bit entered the mine, starting a chain of events which turned an almost 10-foot (3.0 m) deep freshwater lake into a salt water lake with a deep hole. It is difficult to determine exactly what occurred, as all of the evidence was destroyed or washed away in the ensuing maelstrom. One explanation is that a miscalculation by Texaco regarding their location resulted in the drill puncturing the roof of the third level of the mine. This created an opening in the bottom of the lake. The lake then drained into the hole, expanding the size of that hole as the soil and salt were washed into the mine by the rushing water, filling the enormous caverns left by the removal of salt over the years. The resultant whirlpool sucked in the drilling platform, eleven barges, many trees and 65 acres (260,000 m2) of the surrounding terrain. So much water drained into those caverns that the flow of the Delcambre Canal that usually empties the lake into Vermilion Bay was reversed, making the canal a temporary inlet. This backflow created, for a few days, the tallest waterfall ever in the state of Louisiana, at 164 feet (50 m), as the lake refilled with salt water from the Delcambre Canal and Vermilion Bay. The water downflowing into the mine caverns displaced air which erupted as compressed air and then later as 400-foot (120 m) geysers up through the mineshafts.[4] There were no injuries and no human lives lost. All 55 employees in the mine at the time of the accident were able to escape thanks to well-planned and rehearsed evacuation drills, while the staff of the drilling rig fled the platform before it was sucked down into the new depths of the lake, and Leonce Viator, Jr. (a local fisherman) was able to drive his small boat to the shore and get out.[4] Three dogs were reported killed, however. Days after the disaster, once the water pressure equalized, nine of the eleven sunken barges popped out of the whirlpool and refloated on the lake's surface.
