13.13: Enbridge Oil Storage Facility Near Gretna: Small-scale Satellite Image

The Enbridge oil pipeline runs between Edmonton and Gretna in Canada, then continues through northern U.S.A. as the Lakehead system and returns into Canada at Sarnia. This satellite image shows an oil storage facility 1 on the pipeline just north of Gretna 2. A faint impression of the buried pipeline can be seen in sections northwest 3 and southeast 4 of the storage facility, the latter extending into the U.S.A. 5.

Also shown is the international border 6. Note that although Canada and the United States have the same land division system, the two systems do not coincide, resulting in a jog 7 of a north/south road (18 in the U.S.A. 8 and PTH 30 9 in Canada). The sections of the DLS system are obvious 10 with gravel roads along some section lines 11. Quarter sections are usually picked out on the basis of land use differences 12, although most sections in this agriculturally rich area are divided into many fields 13.
