Rosholt, 54, came into prominence in the late 1990s with ascents of hard trad routes like Ruby's Cafe and Desert Gold (5.13a), and was described by acquaintances as a methodical, controlled gambler who enjoyed the adrenaline rush that he got from both climbing and playing poker. In January 2005, he disappeared at the Silverton Hotel and Casino during a trip to Las Vegas.
On November 11th, a group of hikers in the Red Rock National Conservation Area outside of Las Vegas reported finding a spine in the park's Black Velvet Canyon. After initially dismissing the bones as animal remains, the Clark County Coroner's Office ruled last week that they belonged to Rosholt.
The coroner has yet to determine the cause of Rosholt's death, according to the Las Vegas Sun. Police say it's unlikely that foul play was involved; it's unclear whether Rosholt might have fallen while climbing alone.
