Lambi Dehar Mines, Mussoorie, Uttarakhand

The Lambi Dehar mines are an abandoned limestone quarry near Mussoorie, Uttarakhand, worked through the late 20th century in hazardous conditions that caused silicosis and accidents before court-ordered closures ended unregulated mining around the hill station. Folklore describes the ruins as haunted by dead miners, with reports of cries and lights; an oft-quoted toll of 50,000 deaths is unverified legend, not record. Recorded by PRN as a reported/folkloric case — historical context, not proof.
