1930: CAMP VERDE: Discovery at the Sodium Deposit, June 21.
"DISCOVERY PROVES INDIANS MINED SODIUM DEPOSIT."
"Added indications that the early Indians once mined the sodium sulphate deposit near Camp Verde was disclosed there Saturday when workers uncovered one of the most unusual and interesting articles to have ever been found in the ancient tunnels of the well-known deposit."
"Miners in one of the tunnels uncovered a well-preserved headband woven of human hair and archaeologists who viewed the article said that it is as perfect now in weave as it was perhaps a thousand years ago when it adorned the head of some Indian maiden."
"Due to recent finds, which include primitive household objects, archaeologists contend that the ancient peoples made their home in the tunnels of the deposit as they mined underground in search of salt for their food and sodium sulphate for medicinal purposes."
"A small piece of bamboo, recently uncovered in the workings, gives archaeologists more cause for speculation, as no bamboo exists near the Camp Verde vicinity. The small piece of bamboo was shaped and cut in the form of a whistle and was perhaps part of the spoils from a far distant Indian tribe."
"The headband was added to a collection belonging to Mr. Powers, the superintendent, who owns many articles of prehistoric value, including bits of skeletons and mining implements used by primitive workers in the deposit."
