This is a ghost town. One characteristic of a ghost town is that it is completely empty. All of the people who once lived here have left the town. When gold was discovered here years ago, the town was quickly engulfed with people. The town got very crowded. The people were trying to exploit the area for any gold they could find. Many people tried to extract, or take out, gold from the mountains. They searched every day for the hoard of gold hidden there. One reason that gold is so valuable is that it doesn’t corrode or lose its luster. When people stopped finding gold in the area, they abandoned the town and moved on to another. The town still looks the same as it did when it was abandoned in the 1800s.
