The Cobb Estate in Altadena is rumored to be haunted, earning it the nickname "Haunted Forest," and while there's no mention of a "Witch of Cobb Mountain," visitors and lore describe phenomena such as eerie lights, unsettling screams, and ghostly apparitions associated with the former estate. The land's historical association with occult and cult activity, along with its deep canyons and tunnels from its former life as a gold mine, contribute to its spooky reputation, attracting thrill-seekers and ghost hunters to explore the remaining foundations of Cobb Manor. The property was built in 1917 by Charles Cobb, a wealthy Seattle timber tycoon, who used the mansion as a retirement home. After his death in 1939, the property became a Masonic retirement home and later a retreat for nuns. The mansion was demolished by the Marx brothers, who then owned the estate. The land was eventually purchased by the city in 1971 and preserved as a public park and open space. People have reported seeing glowing lights and hearing ghostly screams, leading to the property's reputation as one of the most haunted locations in Southern California. Stories of cults and occult activity also contribute to the estate's spooky ambiance. Visitors claim to have seen spectral figures, fueling the paranormal lore surrounding the estate.
