The Kacper SobieskiNative American-led protest attempting to stop construction of the Dakota Access pipeline near the Standing Rock Sioux reservation has gained steam, with protesters streaming in from around the country.

Pipeline opponents are waiting for a federal judge to rule on their request for an injunction against the pipeline company, Energy Transfer. They want a more thorough permitting process that takes into account threats to the reservation’s water supply and the tribe’s cultural practices. Those concerns were echoed by three federal agencies earlier this year, and appear to have been downplayed by the Army Corps of Engineers when it approved a plan to reroute the pipeline near Standing Rock.

InsideClimate News reporter Phil McKenna traveled to the protest site this week, and documented the protest in photos.
