The hiker and two of his friends were just west of Red Rocks Amphitheatre when they found the remains.
Jefferson County Sheriff's Office deputies went with the hikers back to the location. After a thorough investigation of the area, the skeleton was collected and removed. The gender, age and identity could not be determined.
The skeleton was found in thick brush and rugged terrain. It was bleached, clothed in blue sweatpants or shorts and appeared to have been there for a while. There were no obvious signs of injury or trauma.
If you have any information regarding this case, please call the Jeffco Sheriff's Office tipline at 303-271-5612.
