Carson Hot Springs Golf and Spa Resort, located in Carson, Washington, occupies a scenic location in Skamania County characterized by natural hot spring resources and forested terrain typical of the Pacific Northwest region. The resort was developed to capitalize on the therapeutic qualities of the naturally heated mineral waters present in the area, which have long been recognized for their potential health and wellness benefits. The property was constructed during a historical period when spa and resort development flourished in regions blessed with geothermal resources and natural hot springs. The architectural development of the resort reflects early to mid-twentieth century resort design principles, with facilities designed to accommodate guests seeking relaxation and therapeutic treatments. The main lodge building contains the lobby, reception areas, and common spaces designed to facilitate guest services and create an atmosphere of hospitality and leisure. Upstairs areas included guest rooms and private spaces arranged in hallways that facilitate circulation throughout the property. The resort developed a regional reputation for providing quality accommodations and access to therapeutic mineral springs. The paranormal history of Carson Hot Springs Resort is inextricably connected to the life and death of Isadore St. Martin, whose tragic murder in 1910 established the foundation for the location's supernatural reputation. The circumstances surrounding St. Martin's death involved violence and trauma that left an indelible mark on the property. The presence of Isadore St. Martin has been repeatedly documented by paranormal investigators and witnesses throughout the resort, with manifestations occurring in multiple locations. The spirit of his wife Margaret has also been extensively reported, with her apparition appearing with particular frequency in the lobby area and the second floor hallways. These two spirits appear to remain bound to the location where their tragedy unfolded, with their continued presence suggesting emotional attachments or unresolved circumstances connected to St. Martin's violent death. The paranormal phenomena at Carson Hot Springs have prompted both practical and spiritual responses from property management and community authorities. The third floor of the resort was eventually sealed and blocked off to guests following numerous paranormal occurrences and disturbing reports from visitors who had occupied rooms on that level. The decision to restrict access to the third floor represents an acknowledgment of the intensity and nature of the paranormal phenomena manifest in that area. This action reflects the seriousness with which paranormal reports were taken by management and the apparent belief that containment of the spiritual activity was necessary for guest safety and property operations. Paranormal investigators have identified the resort as a documented hotspot for paranormal activity. Carson Hot Springs Golf and Spa Resort continues to operate as a hospitality destination, with management maintaining awareness of the property's paranormal history and reputation. The resort has become known among paranormal enthusiasts and ghost hunters throughout the region as a legitimate site for investigating authentic supernatural phenomena. While the third floor remains restricted from general guest access, paranormal investigators conducting formal studies at the property have been permitted to investigate those sealed areas under controlled conditions. The tragic history of Isadore St. Martin and his wife Margaret is preserved in both historical documentation and paranormal records, maintaining the memory of the event that appears to have created conditions for continued spiritual presence.
