Sitting just four miles below the Continental Divide and some 25 miles northwest of Helena, Montana is the once-thriving mining camp of Marysville. The settlement got its start when Irishman Tommy Cruse discovered a rich vein of gold on Silver Creek in 1876. A placer miner who had been working downstream, Tommy continued upstream hoping to find the mother lode, and lo and behold, was the lucky man to find it.
