This Friday, the U.S. District Court for the District of Columbia is expected to issue a decision on the construction of the Dakota Access Pipeline, which would carry around half a million barrels of crude oil per day across four Midwestern states.

While the hearing will be in D.C., tribal and environmental activists have gathered in North Dakota for weeks, pledging to stop the pipeline from entering the Missouri River. Some have taken separate direct actions at nearby construction sites.

Grist’s been capturing the scene on the ground:

Activists swarmed a Dakota Access construction site on Tuesday morning, unfurling banners and leading several dozen people, including Green Party presidential candidate Jill Stein, in song and prayer. Law enforcement officers stood back and observed the scene as two activists chained themselves to excavators; construction workers vacated the site without comment.

An indigenous activist locked to an excavator takes a drink of soda, while two others spray paint "Black Snake Kills" on the blade. "Black Snake" refers to an old Lakota prophecy, about a black snake that would come to the prairie with the ability to destroy the world — or unify it.
