Other Notable Parallels
A number of sub-national and international borders are defined by, or are approximated by, parallels. A major reason why latitude makes for convenient borders in the northern hemisphere is because it is readily measured by sighting the North Star.
| Parallel | Description |
|---|---|
| 70°N | On Victoria Island, Canada, two sections of the border between Northwest Territories and Nunavut. |
| 60°N | In Canada, the southern border of Yukon with the northern border of British Columbia; the southern border of Northwest Territories with the northern borders of British Columbia, Alberta and Saskatchewan; and the southern border of mainland Nunavut with the northern border of Manitoba, leading to the expression "north of sixty" for the territories. |
| 54°40'N | The border between 19th century Russian territories to the north and conflicting American and British land claims in western North America. The conflicting claims led to the Oregon boundary dispute between Britain and the United States, giving rise to the slogan "Fifty-four forty or fight." |
| 52°N | In Canada, part of the border between Newfoundland and Labrador and Quebec. |
| 51°N | The southern limit of Russian America from 1799 to 1821. |
| 49°N | Much of the border between Canada and the United States, from British Columbia to Manitoba; "49th parallel" is a common expression for the border, though the majority of Canada's population actually lives south of the parallel. |
| 48°N | In Canada, part of the border between Quebec and New Brunswick. |
| 46°N | In the United States, part of the border between Washington and Oregon. |
| 45°N | Part of the border between Canada (Quebec) and the United States (New York and Vermont) is approximated by the parallel. Also, in the United States, it approximates most of the border between Montana and Wyoming. |

| 42°N | Originally the northward limit of New Spain. In the United States, the southern borders of Oregon and Idaho where they meet the northern borders of California, Nevada and Utah. The parallel also defines much of the border between Pennsylvania and New York. |
| 41°N | In the United States, part of the border between Wyoming and Utah, the border between Wyoming and Colorado, and part of the border between Nebraska and Colorado. |
| 40°N | In the United States, the border between Nebraska and Kansas. The parallel was originally chosen for the Mason-Dixon Line, but the line was moved several miles south to avoid bisecting the city of Philadelphia. |
| 38°N | The boundary between the Soviet and American occupation zones in Korea, and later between North Korea and Republic of Korea, from 1945 until the Korean War (1950–1953). |
| 37°N | In the United States, the southern border of Utah with the northern border of Arizona. The southern border of Colorado with the northern borders of New Mexico and Oklahoma. The southern border of Kansas with the northern border of Oklahoma. |

Geographically it is a Westward extension of the border between Virginia and North Carolina and part of the border between Kentucky and Tennessee. |
| 36°N | In the United States, a short section of the border between the Missouri Bootheel and Arkansas. |

Famous quotes containing the words notable and/or parallels:
“In one notable instance, where the United States Army and a hundred years of persuasion failed, a highway has succeeded. The Seminole Indians surrendered to the Tamiami Trail. From the Everglades the remnants of this race emerged, soon after the trail was built, to set up their palm-thatched villages along the road and to hoist tribal flags as a lure to passing motorists.”
—For the State of Florida, U.S. public relief program (1935-1943)
“If, while watching the sun set on a used-car lot in Los Angeles, you are struck by the parallels between this image and the inevitable fate of humanity, do not, under any circumstances, write it down.”
—Fran Lebowitz (b. 1950)
