Old trail markers were replaced. Ground that had been impossible to see from the air in 1974 was now in the burned and regenerating zones, open for hundreds of yards in every direction.
None of it produced Daniel Voss. By 2005, 31 years after his disappearance, the case had achieved a kind of ambient notoriety specific to the genre, a presence in the early true crime forums that had bloomed on the new internet.
A mention in two books about national park missing persons, a short entry on a website called locations unknown that listed it alongside 43 other unresolved park disappearances.
On the forum threads, the theories accumulated like sediment. He had fallen into a hydrothermal pool and the body had been dissolved by the acidic water.
He had been attacked by a bear. The evidence scattered and eventually covered by the 1988 fires.
