On August 7, 1988, journalist Keith Reinhard disappeared while writing a novel about another man’s disappearance.
He has never been found.
During the summer of 1988, journalist Keith Reinhard moved to the tiny Colorado mountain town of Silver Plume to write, reflect, and regenerate.
With his 50th birthday approaching, Keith was determined to recapture his youth, overcome his fear of heights, and begin writing a novel.
Keith Reinhard was fascinated with the history of Silver Plume - a former mining town haunted by a century-old pattern of bizarre disappearances and death.
Reinhard became obsessed with the mysterious disappearance of Tom Young, another Silver Plume resident who vanished the year prior. Young had occupied the same storefront that Keith now operated. Working within these same walls, Tom Young became the basis of Reinhard's novel.
At 5 PM on August 7, 1988, Keith closed up his shop for the day, telling friends that he was hiking to the top of nearby Pendleton Mountain - a hike Reinhard knew would take at least six hours.
He never returned.
Despite one of Colorado's largest land and air search missions, no trace of Keith Reinhard has ever been found.
Today, a series of bizarre speculations, rumors and sinister theories about what actually happened to Keith has given rise to a story of legend in the small community of Silver Plume. Did the disappearance of Tom Young have any relationship to his own? Is it possible Keith set up his own disappearance? Did he commit suicide? Was he murdered?

Residents of Silver Plume don't take kindly to the term "ghost town."
But there is no better description for the once-bustling mining center. Since the 1890s silver crash, its population has plummeted to a mere 130, largely a melting pot of transplants from around the country - teachers, artisans, and builders.
The town has an eerie, windswept vacantness. Steep canyon walls sandwich the valley in shadow. The north side of town receives as little as two and a half hours of direct sunlight a day in winter; the south doesn't see the sun at all for about six weeks a year. To add to its darkness, Silver Plume is haunted by a century-old pattern of bizarre and mysterious death.
A granite shrine looming on a cliff above town serves as a reminder of its macabre legacy.
Clifford Griffin, owner of the 7:30 Mine, died by a bullet to the head in 1887. Townspeople have argued for a century whether Clifford was murdered or committed suicide.
Keith Reinhard's untimely disappearance has become yet another bizarre footnote in a town already shrouded in mystery.
