Boulder Hot Springs Hotel and Resort occupies distinctive setting in Boulder, Montana, selected for naturally heated mineral waters emerging from geothermal sources. Developed beginning in 1863, the property capitalized on therapeutic properties attributed to hot springs. The region's geothermal features attracted miners, ranchers, and businessmen seeking mineral bath treatment through a practice rooted in centuries of traditional water cure medicine. Now operating continuously for over one hundred fifty years, the facility reflects sustained attraction of geothermal hot springs as therapeutic and recreational destinations. The paranormal reputation derives from legendary presence of Simone, identified as a woman who worked at the resort as a prostitute during the nineteenth or early twentieth century. According to widely circulated accounts, Simone became involved in violent altercation with a Butte mining executive, culminating in her being stabbed in the resort office. The specific circumstances remain undocumented, though accounts suggest economic exploitation or personal humiliation. The fatality created a ghost story centered on Simone's untimely death and alleged spiritual attachment to the property. Paranormal manifestations attributed to Simone concentrate primarily in third-floor windows. Witnesses report observing a woman in a white gown visible at the window, a figure suggesting awareness and possible communication with observers. Resort owner Anne Wilson Schaef reportedly encountered Simone in hallway manifestation, with the apparition displaying mischievous and caring expression. Guests swimming in the resort pool have reported observing the white-gowned woman watching from the third-floor window, behavior suggesting protective concern or possessive attachment to the property. The identity and historical authenticity of Simone remain substantially unverified. No documentary evidence establishes identity of any prostitute by that name, confirms death at the resort, or documents the violent incident. This absence of corroboration has led researchers to question whether Simone represents an actual historical person or constitutes paranormal legend of partially fictional origin. However, paranormal researchers note that consistency of sightings and specific localization to third-floor windows suggest genuine manifestation regardless of historical accuracy of the narrative. The professional and social context of Simone's employment reflects historical conditions in which sexual services were frequently available at such establishments. Prostitute workers were positioned as simultaneously economically valuable and socially stigmatized, creating vulnerability to violence and exploitation. The violent death attributed to Simone exemplifies occupational hazards faced by women in vulnerable economic positions during that historical era. The geothermal setting provides environmental context distinctly different from other haunted locations. Naturally occurring hot water creates atmospheric warmth, mineral odors, and humidity potentially impacting perceptual psychology. Some skeptical observers propose environmental characteristics might facilitate misinterpretation as paranormal, but paranormal researchers note specific localization to particular windows and consistency of descriptions suggest manifestations transcending simple environmental misperception. Paranormal documentation includes representation in paranormal literature and regional collections. Researcher Karen Stevens documented the haunting in "More Haunted Montana." Inclusion in paranormal databases has established Boulder Hot Springs as a recognized haunted site within Montana's paranormal geography. The commercial establishment has acknowledged paranormal reputation in promotional materials, recognizing that the haunting narrative attracts paranormal-interested visitors. Present-day Boulder Hot Springs operates as resort and spa facility, continuing its nineteenth-century therapeutic mission. Guests encounter the Simone legend as documented history, with the third-floor remaining accessible to interested guests and investigators. Visitors continue reporting experiences consistent with historical paranormal accounts.
