No, the Treaties do not say different. The Treaty of 1868 is basically the treaty that all sides agree is the proper one. It placed the northern border of the reservation at the 46th parallel and the Missouri River. In 1873, there was an executive order extending the border north to the Cannon Ball River. The pipeline is north of the Cannon Ball River and NOT on reservation land. The biggest problem the tribes have with the actions after the Treaty of 1868 was the treaty of 1877 that took the Back Hills away from the Sioux and also broke up the whole reservation into smaller reservations. The Sioux did not ratify this treaty as required by the Treaty of 1868. I agree with them that they should not agree to the changes since they were not done in accordance with the requirements of the Treaty of 1868. The pipeline has never been on reservation land and is still not on reservation land. You might not agree with the Treaty of 1868 yourself but Sitting Bull and Red Cloud did.
