The Pioneer Park/Henry Webber House in Aspen is associated with the ghost of Harriet Webber, who reportedly died in 1881 from an accidental strychnine overdose, though this occurred four years before the house was built. The house is described as a real haunted place, with visitors reporting unexplained phenomena like knocking and the sense of someone standing behind them. The main ghost associated with the house is Harriet Webber, wife of the house's builder. Harriet died in 1881 from a strychnine overdose, which was ruled accidental, but the timing is somewhat confusing as the house wasn't built until 1885. Visitors have reported hearing knocking sounds, footsteps, and loud bangs, according to YouTube. Some people have reported feeling like someone is standing right behind them, particularly near the mineral exhibit in the location.
