The largest salt mine of the Alliance was not far south of the Capital City, and smaller salt mines could be found everywhere. The eastern section of Lake Texcoco was divided by a dike, where there were hyper-saline lakes, and many high-quality salt springs were distributed around the mountains and deep valleys, also a product of volcanic activity.
The Mexica Alliance was never short on salt. Salt was an important trade good for the Mexica people and brought in enormous revenues. From the eastern to the southern shores of the lake region, there were many villages engaged in salt production. The large salt mine had also developed from these salt-producing villages. It was closest to the bustling Lake Capital City, which made transportation extremely convenient, so the population gathered, and the production capacity was the highest, able to supply the demand for salt of hundreds of thousands of people.
