The Hallstatt salt-mine is the oldest and longest producing mine on the planet, 7.000 years of mining! The mine is very exciting for archeologists also as some very old and famous thing have been found there - preserved by the salt. For exmaple in 2003 the oldest wooden ladder was in Europe found (it is now 3.350 years old!). As you can see the specimen is in fine condition. Hundreds of very fine, lustrous crystals are on the whole front of the item. The gyspum is mostly clear with fine termination. Looking closer you can see that some crystals are bended, very cool I think. So this is very historic stuff from an important location.
