Firefighters brought in a ladder truck and brought the man to safety.
"A firefighter climbed up the ladder as far as possible, finally coaching (the man) down far enough to get onto the ladder. He had held onto his boxers and actually paused and managed to get them back on before getting onto the ladder," Rummel told KKTV.
The man, who was not identified, was taken by an ambulance to an area hospital for evaluation, the television station reported.
The man's father told police he did not know why his son was in Colorado but added he had been struggling with narcotics, KDVR reported.
Police did not disclose what motive the man had for climbing the power pole.
