1970 – Present
Secretary Walter J. Hickel restored the bison to the Interior seal in 1969 and the NPS redesigned its badge to match in 1970. These gold "bison badges" are marked "National Park Ranger" and the uniform standards restricted their use to law enforcement rangers. In 1977, the badge became part of the men's Class A uniform. The next year women were included when they were authorized to wear the same "green and gray" uniform as the men.
Gold-filled metal. L 4.9, W 4.1, T 1 cm
