April 20 – On this day in Montana History in 1887 the town of Castle between the Little and Big Belt Mountains about 75 miles north of Bozeman was named. Between 1886 and 1890 surrounding mines yielded about $1 million in silver. The town thrived with churches, schools and even home delivery of milk. It was one of the richest in Montana. But about 10 years later silver prices plummeted and as the local newspaper reported, “One day, the local boarding house served 135 men. Three days later, it fed only three.” Few people remember the once promising community today.
