Up for bid is a Calcite Pseudomorph of a Glauberite crystal from the Camp Verde Salt Mine in Arizona. This specimen fluoresces Cream under all UV wavelengths and is also phosphorescent.
From Mindat: The Camp Verde Salt Mine is one of the oldest known mines in the United States and some experts note that the area was likely worked for salt as long as 2000 years ago. Rare artifacts have shown that the mine was worked for salt at least before the arrival of Columbus (pre-Columbian) in the 14th and 15th centuries. The mummified body of an Indian miner was found in the underground workings during the most active mining period in the early 20th century. The establishment of Ft. Verde in 1871 brought new attention to the salt deposit and some of this was used for human consumption but the majority was used as stock salt. In the 1920s, the Western Chemical Company operated an open pit on the property. The ore was used in the processing of paper pulp. Later efforts in the early 1930s by the Arizona Chemical Company employed underground mining techniques and 14 tunnels were driven in horizontal strata for several hundred feet and followed rich layers of salt. At the time, about 75 men were employed (about half were Apache Indians) and the mine produced nearly 100 tons of "salt cake" daily, making the Camp Verde Salt mine the most productive in the country. This success was short-lived and duty-free and purer German ore entered the market in 1933 and essentially forced the closure of the mine. Attempts were made as late as the 1960's to market the deposit but current market needs demand 99% purity and the Camp Verde salt deposit is limited to 92% purity. Additionally, much larger deposits in the US and Canada exist and the mine has been dormant ever since.
