Avery Island, LA; view to the south. On cloudy days,
its "high" elevation causes it to appear above the clouds as an island. |
The first salt mine; and continuously operating since
1791. |

Through the trussels is the site of the first commericial
salt mine on this site in 1791. |

Touring the facilities |
Entering the Steam Room |
|
|
Steam room. The original steam engine, purchased
and used in 1898, is still in use today and runs the hoist. Mining occurs
down to the 1,300-1,600' levels. (Although the dome extends to 40,000' in
depth). |
Overlooking the miles of conveyor belts, with shaft
for mineral extraction. |
|
|
Conveyor belt for packaging the salt. |

Tour Guide, Rod Etie, with the hoist signals. There
is no direct visibility from steamroom to hoist - requiring signals! |
All things enter the mine through the hoist, including
machines and people. |

Waterway allows barges to dock directly on site. |
Barge being filled with salt. Note waterline. |

|
The Blue Lagoon, a famous sinkhole. |
Rod explaining the water monitoring system, i.e.
if there are water leaks into the mine, water levels will drop at the surface. |
|
|
Manometers for measurement. Behind right, water level
is at the surface, to the left, water level is 27' below the surface
reflecting the subsurface geology. |
Avery Island has no caprock and weathers away at
the surface due to water infiltration. Sinkholes abound. |
|
|
Cargille Deicing Technology has operated the mine
since 1997. |
This mine was important during the Civil War. |
