Remarkably easy to find, the southwest corner of Wyoming is marked by a red stone monument inside a 90 degree bend in a lonely paved road that follows the border. The monument is in a terrifically scenic location, with a view of the snow-capped-in-July Uinta Mountains to the south. This border was surveyed in 1873 by astronomer A.V. Richards, and was placed on the 41st parallel north of the equator and the 34th meridian east of Washington, D.C. (again, screw that Greenwich!).
