Analysis

The helicopter tail rotor contacted a forest service sign post during landing. The pilot was aware of the post when landing but landed near it for convenience in refueling. The landing was on a slope and the nose of the acft started sliding on the slope. The pilot raised the acft but the nose continued to yaw which caused the tail rotor to hit the post. The helicopter then yawed and rolled over.
