西经104度线
西经104度线是本初子午线向西104度的经线,是为西经104°。此线经线由北极点起穿过北冰洋、北美洲、太平洋、南冰洋以及南极洲直到南极点。此段半圆路径长20,003,932千米(12,429,867英里),于赤道与本初子午线距11,577千米(7,194英里)远。[1][2]
于美国,北达科他州、南达科他州、内布拉斯加州西侧州界与蒙大拿州、怀俄明州的东部州界以华盛顿子午线为准的西经27度线为界,同时该经线距格林尼治为准的西经104度线西方约数英里远。[3]:125-126:129-130:132[4]:172在科罗拉多州,西经104度线大致界定了由南落基山脉保护的高原地区的东部范围。[5]
