The account
Local tradition says miners taking a short cut through the cemetery saw them in the 1880s, but no newspaper of that time mentions them.
The sceptical view
Proposed explanations include reflected lights from Silver Cliff and Westcliffe, phosphorescent minerals and the eye's own tricks in deep darkness.
The researched reading
A long-running ghost-light legend at a dark mountain cemetery. Reflected and distant lights, the tricks of dark-adapted eyes and a good story explain it well.
| Explanation | Weight | Why |
|---|---|---|
| Something in the surroundings | 38% | The cemetery sits on open ground with the lights of Silver Cliff, Westcliffe and passing vehicles in view; reflections off polished headstones and distant lights glimpsed through gaps are the explanations tested most often by visitors. |
| Perception, memory or mind | 26% | In deep darkness the eye produces drifting spots and the autokinetic effect makes faint fixed lights wander; visitors arrive expecting to see the lights. |
| A cultural story | 18% | Miners’ lamp ghosts are a common motif; the story spread through a 1956 local newspaper piece and National Geographic in 1969, and became a tourist legend. |
| A known natural phenomenon | 10% | Reports that the lights persisted when the towns were blacked out point some observers to natural causes such as phosphorescence, though none is demonstrated. |
| A hoax or fabrication | 4% | Pranks with flashlights in a cemetery are easy, though they cannot explain decades of reports. |
| Genuinely anomalous | 4% | No recording or controlled observation shows a light that ordinary causes cannot explain. |
Official position: No official investigation; the popular account presents the lights as unexplained ghost lights.
