A blizzard which began in the night continued throughout the day. Second hand information was received that security at the Seven Councils camp was attempting an evacuation effort due to conditions at the camp.  However, Emergency management and law enforcement officials had received no phone calls or other requests for assistance from the camp or Standing Rock Tribal officials.  Contact was made with the Standing Rock Tribal Emergency Manager and Sioux County Emergency Manager who could provide no additional information on conditions at the camp.  The Standing Rock Tribal Emergency Manager advised that emergency shelters had been established at the Casino pavilion and at the schools in Ft. Yates.  ND Dept of Transportation snow plows were assigned to attempt to clear Hwy 1806 to the camp.  A snowplow did reach the camp at approximately 1:00 pm, having plowed Hwy 1806 from the south.  A BIA law enforcement officer had followed the plow and checked on conditions at the camp.  BIA reported that while people were leaving the camp in their own vehicles once the road was opened, no emergency existed in the camp.  The Dept of Transportation was going to continue to plow in the area until approximately 7:00 pm if conditions allowed.
