On foggy nights, if you look at the cemetery, you can see the swinging lights of a coal miner's lanterns, you can sometimes hear whistling in the wind, supposedly that of the coal miners. It is also reported that a white horse is seen trotting around headstones. Regan of APART of Washngton indicated this may be a phenomenon called Ignis Fatuus
that can be caused by gaseous exhalations from moist ground (see comments below).

History
The cemetery was established in the 1880s on a hilltop site at the edge of the thriving mining town of Black Diamond, then the biggest settlement in King County outside of Seattle. The cemetery is a complex cultural landscape, capturing the tremendous ethnic diversity of the town’s early history, in the surnames of those buried there, as well as in the languages, religious and fraternal organization affiliations, and styles of the grave markers.
