Est. 1911 · First Tuberculosis Sanatorium in the Upper Peninsula (1911) · TB Epidemic Treatment History — Marquette County · Main Building Demolished 2002 · Michigan Mining Journal TB Historical Documentation (2021)
Morgan Heights Sanatorium opened in 1911 in Marquette County's Morgan Meadows area along what is now County Road 492, positioned to serve the Upper Peninsula's substantial working-class population during the tuberculosis epidemic of the early twentieth century. TB was the leading cause of death nationally at the time, and the industrial communities of the UP — miners, timber workers, and their families — were among the hardest-hit populations.
The Marquette Mining Journal documented the facility's history in a 2021 piece on TB as the 'forgotten plague' of Marquette County. Patients at Morgan Heights received the treatments standard to the era: enforced bed rest, fresh air protocols, and in more aggressive phases, electric-shock therapy and morphine-based sedation that exceeded therapeutic doses. These approaches, while consistent with period medical practice, contributed to mortality among patients who might otherwise have survived longer.
The sanatorium operated for decades as the primary tuberculosis treatment center for the UP. By the mid-twentieth century, antibiotic treatment had largely eliminated the need for institutional TB facilities, and Morgan Heights declined in use. The main building was demolished in 2002. Two original brick structures — ancillary buildings from the original campus — remain standing on the site along CR 492.
The open field surrounding the surviving structures is identified by Travel Marquette as among the most haunted locations in Marquette County, drawing paranormal investigators who have reported visual phenomena across the grounds. The site has no formal public access program.

Hundreds of apparitions reported crossing open fieldRecurring apparition in flannel shirt in basement of surviving brick structureVisual phenomena across former campus grounds
The paranormal reputation of Morgan Heights Sanatorium centers on the open field surrounding the two surviving brick structures, where investigators describe large numbers of apparitions — a phenomenon that 99wfmk investigators reported as 'hundreds' of figures crossing the grounds. This type of mass-apparition account is relatively unusual in regional paranormal documentation and has kept the site prominent in UP haunted-location surveys.
Among the more consistently described figures is a presence identified by investigators as wearing a flannel shirt, encountered in the basement level of one of the surviving brick outbuildings. The flannel-shirt detail has appeared in multiple accounts and is treated by investigators as a recurring rather than one-time observation.
Travel Marquette, the county's official tourism bureau, includes Morgan Heights as among the most haunted locations in Marquette County — an unusual endorsement from an official tourism body that reflects the site's embedded status in the region's dark-history landscape.
The demolition of the main building in 2002 removed the structure where the majority of patient deaths occurred, and investigators note that the field activity may represent presences that once occupied the now-absent main building. No formal investigation organization currently holds regular access to the site.
