The meridian 141° west of Greenwich is a line of longitude 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 141st meridian west forms a great circle with the 39th meridian east. Most of the border between Alaska, United States and Yukon, Canada is defined by the meridian, meaning the western extremity of Canada lies on this meridian.
