Roseville police say a man's body was found down an embankment along the Miner's Ravine bike trail Tuesday morning.
Investigators have not identified the man, only saying he was in his 30's. It was not immediately clear how the man died.
Police said a cyclist made the discovery.
Part of the trail, by East Roseville Parkway and Rocky Ridge Road, was closed for part of the day as detectives looked over the scene.
