Entry No. 23 — the Butte file — filed under: soak

Boulder Hot Springs

A rambling Mission-style grand hotel that Butte mining millionaire James A. Murray built out in 1910-1913, where geothermal water has drawn soakers since gold miners came to ease their muscles in the 1860s. The grounds hold a cooler outdoor mineral pool plus separate men's and women's indoor plunges and steam rooms, where the hot pools run a scalding 103-106 degrees. The faded hotel, on the National Register of Historic Places since 1979, sits against the foothills and carries a reputation for being haunted, giving the soak an off-kilter, time-warped feel.

The move: Pay for a soak session and drift between the warm outdoor pool and the historic indoor plunges as the foothills go dark around the old hotel.
