Miners faced a disease called scurvy. Scurvy is caused by not enough vitamin C in the diet. It typically takes at least a month of little to no vitamin C before symptoms occur. Early symptoms include weakness, feeling tired, curly hair, and sore arms and legs
Comstock lode was the first major silver discovery. Discovered under what would become one of the most important gold camps in the west – Virginia City, on the eastern slope of Mt. Davidson, the mines would yield more than 500 million dollars of silver and gold
They usally spent all their life savings during the gold rush to get tools, a place to sleep, etc so it they didn't find gold and did not make any money they would have had a horrible time. It was also very lawless in some parts. It was also very heavily over populated.
