STEAM Spotlight: Ringing Rocks
Up a rough and rocky road off I-90 about 18 miles east of Butte, a fascinating discovery awaits those willing to make the often-treacherous drive. Rising from a small dusty parking lot is a roughly 1200 square foot boulder field, which, to most people, looks like an ordinary pile of big rocks. But if you take a hammer to them, you’ll hear the distinct sound of a train whistle. Or a bell. Or a chime.
