{"id":1782,"slug":"ringing-rocks-montana","story":[{"heading":null,"paragraphs":["On a ridge east of Whitehall, in the granite country of Montana's Boulder Batholith, the Bureau of Land Management keeps a field of loose boulders that does something geology does not advertise: strike one with a hammer and it rings — a clear, bell-like tone from a jumble of igneous rock that looks no different from any other. The field covers a few acres; the sound is startling up close."]},{"heading":"What is and isn't settled","paragraphs":["Only a portion of the boulders ring, and a stone pried loose and carried off loses its voice entirely — the pile itself appears to be part of the instrument. The mechanism is still debated; stresses locked in as the rock cooled are the usual suspect, but the file's honest position is that the phenomenon is documented and the explanation unfinished. Montana's field is one of a handful of ringing-rock sites in the country — Pennsylvania's better-known county park is its eastern sibling — and the BLM asks visitors to leave the stones in place, since a carried-off rock is a dead instrument."]},{"heading":null,"paragraphs":["The site is open country, visited the way it has always been visited — with a hammer.
