Boulder authorities are asking for the public's help to identify a body pulled out of Boulder Creek.
An autopsy is scheduled today on the body, discovered when someone floating down the creek on an inner tube bumped into it yesterday.
Boulder County Coroner Tom Faure says the man had no identification, and no obvious signs of trauma.
Investigators spoke with people close to the creek, and in nearby Central Park, but were unable to determine the man's identity.
Authorities also aren't sure how long the body was in the creek before being found.
