Almost exactly a decade since the start of the Standing Rock protests against the Dakota Access pipeline gained national and international attention, new disputes are simmering over tribal rights in the Black Hills of South Dakota.

Earlier this month, an environmental organization and a Native American advocacy group sued the US Forest Service, claiming that an exploratory graphite drilling project on national forest land threatened a recognized ceremonial site on mountain meadows known as Pe' Sla, or Reynolds Prairie.
