HistoryA character grade: shown, never part of Pine Ridge’s overall grade.
South Dakota towns list more on the Register than most of the country (a typical South Dakota town has 37.3 per 10,000 residents, the U.S. 2.4), so Pine Ridge’s 0.0 sits below most of its state (15% of South Dakota towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

What stands out about Pine Ridge’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
The community was named for the pine trees on the ridge surrounding the town site. An early variant name was Pine Ridge Agency.
The Pine Ridge reservation was the location of a violent shootout between FBI and activist Native Americans in 1975. FBI agents Jack Coler and Ronald Williams were killed in the initial firefight, while activist native Joe Stuntz was later shot by a police sniper. Native/Activist Leonard Peltier was later convicted of the murder of the agents and sentenced to life in prison, but there has been debate around his innocence.
