What’s in a Name?

The Beryl Mountain Mine was one of a number of mines located near Hahns Peak, north of Steamboat Springs. Beryl's primary commodity was zinc, although tertiary ore included copper, gold, lead and silver. Located and operated on National Forest, the Beryl Mountain Occurrence later became part of the Tom Thumb Mine.
