At approximately 2:45 pm, a group of approximately 20 vehicles left the camp and drove to the area of the Ft. Rice boat ramp. The protesters (estimated at 40-50) then marched in the ditch to the area just south of the Ft. Rice campground area where they encountered a line of law enforcement officers. The protesters staged a demonstration for approximately 10 minutes and then returned to their vehicles and drove back to the camps. There was no significant confrontation with law enforcement and no arrests were made. At approximately 5:00 pm, a report was received that approximately 100+ protesters were present at the north camp site (where the pipeline route is to cross Hwy 1806). Law enforcement responded. The protesters were ultimately estimated to be approximately 150+. They held a demonstration or prayer ceremony. There were reports of up to 20 protesters who may have crossed the fence line onto private property but law enforcement did not make contact with any protesters on private property. By approximately 6:15 pm, the protesters had left and returned to the camps. There was no significant confrontation with law enforcement and no arrests were made.
