A climber who was half-naked -- and possibly high on mushrooms -- was rescued from the First Flatiron on Friday afternoon, according to the Boulder County Sheriff's Office.
At 12:35 p.m., officials received a call from a climber saying his friend was "not acting right" and required assistance as the two were climbing the First Flatiron. Both men were 25 and visiting from Missouri, according to a news release.Emergency crews were able to retrieve the climber, who was treated and released from Boulder Community Hospital.
Deputies found psilocybin mushrooms -- a hallucinogenic -- on the climber who called the rescue in and arrested him on suspicion of felony possession of a controlled substance.
Investigators say the rescued climber may have been under the influence of the mushrooms and could face drug charges.
Also, deputies say they think a civilian may have been bitten by one of the climbers during the rescue .
