Members of Idaho’s Native American tribes from around the state, along with supporters, are gathered on the state Capitol steps this morning to support the Standing Rock Sioux tribe’s challenge to the Dakota Access pipeline; it’s one of several such gatherings in multiple states. At the Idaho rally, people held signs with slogans including, “Sho-Pai Stands With Standing Rock,” “Protect Our Water,” “Honor The Treaty,” and “Nimipuu Stands With Standing Rock,” which refers to the Nez Perce Tribe in north-central Idaho.

Tribal members held sunrise prayers at Quarry View Park this morning, then a group of runners from Duck Valley ran an eagle staff down Warm Springs to the state Capitol, accompanied by a motorcycle police escort. At the Capitol, there’s drumming, songs, and speeches. More than 75 people had gathered as of 9:30 a.m., and more still were arriving.

The event is part of the #NoDAPL solidarity effort to back the Standing Rock Sioux; some Idaho tribal members also have traveled to North Dakota, where a giant encampment has set up in the path of the pipeline. A federal judge is set to rule on the tribe’s legal challenge to the pipeline today. The four-state, $3.8 billion pipeline would run less than a mile upstream of the tribe’s reservation, raising concerns it could impact drinking water for more than 8,000 tribal members and millions downstream.

The protests have been peaceful, but protesters and private security guards have skirmished on private land, where the tribe says construction has disturbed ancient sacred sites; there also have been arrests. The AP has an explainer story on the issue online here.
