The proposed Keystone XL pipeline starts from the same area in Alberta, Canada, as the Phase 1 pipeline. The Canadian section would consist of of new pipeline. It would enter the United States at Morgan, Montana, and travel through Baker, Montana, where American-produced oil would be added to the pipeline; then it would travel through South Dakota and Nebraska, where it would join the existing Keystone pipelines at Steele City, Nebraska. This phase has generated the greatest controversy because of its routing over the Sandhills in Nebraska.
