Nopeming has a special place in the paranormal of Duluth. The Travel Channel sent a team in 2015, as featured in the link above. The Duluth News Tribune covered its history in a 2017 article.
The Nopeming facility was in use until Nov. 25, 2002. Friends of mine have laughed that rooms and spaces shown on ghost hunting shows holding tormented souls were, in fact, the places they worked as food service workers in high school.
