120th meridian west
Template:Short description Script error: No such module "Unsubst". Template:Location map-line Template:Side box
The meridian 120° west of Greenwich is a line of longitude[1] that extends from the North Pole across the Arctic Ocean, North America, the Pacific Ocean, the Southern Ocean, and Antarctica to the South Pole.
The 120th meridian west forms a great circle with the 60th meridian east.
In Canada the border between British Columbia and Alberta is defined by the meridian north of where it intersects the Continental Divide of the Americas, and in the United States part of the border between California and Nevada follows it.
This longitude is the eastern limit of the Oakland Oceanic and Tahiti flight information regions, as well as the western limit of the Mazatlan Oceanic FIR.
The mean solar time at this meridian determines the time for the Pacific Time Zone (UTC−08:00) during standard time. Most of the year however, it is the meridian for Alaska Daylight Time, as daylight saving time is observed for two-thirds of the year.

Discrepancies at the California–Nevada border

When California attained statehood in 1850, it adopted 120th meridian west as its eastern border.[2][3] Between 1855 and 1900 there were six surveys to locate 120 degrees, with each locating the line of longitude differently.[4] In 1872, Alexey W. Von Schmidt undertook the survey of the state line. He marked his survey line with stones, wood, and iron markers; the only one who placed such markers[4] A new survey in 1893 showed that the Von Schmidt line was 1,600 to 1,800 feet west of the actual 120 degrees. However, California and Nevada both recognize the 1872 Von Schmidt survey and the 1893 survey as the state line.[4] Google maps shows that the Verdi, Nevada California–Nevada boundary marker, located at Script error: No such module "Coordinates"., is approximately Script error: No such module "convert". west of 120 degrees longitude, with a similar deviation along the length of the line from Oregon to Lake Tahoe.

On the same day that it admitted California, Congress established a territorial government in the area immediately to the east. The organic Act for that new Territory -- which was then called Utah -- stated that it was to be "bounded on the west by the State of California." Act of Sept. 9, 1850, 9 Stat. 453. Eleven years later, the Territory of Nevada was created out of Utah. Congress indicated in the organic Act that Nevada might include portions of what was then California, but with the proviso that "so much of the Territory within the present limits of the State of California shall not be included within this Territory until the State of California shall assent to the same by an act irrevocable without the consent of the United States. . . ." Act of Mar. 2, 1861, 12 Stat. 210. No assent was ever given by California. Accordingly, when Nevada was admitted as a State in 1864, its western boundary and California's eastern one remained congruent.").Script error: No such module "Check for unknown parameters".
