Explanation:

[STC001970] The Four Corners Monument attracts people from all over the world, including Americans, who travel hundreds of kilometers into the desert merely to stand at a site that was positioned improperly. An unusual quadripoint formed by the states of Arizona, Utah, Colorado, and New Mexico, Four Corners is commonly referred to as simply “The Corners.” More than 250,000 people visit this phenomenon, the only such quadripoint in the U.S., but because surveying technology was not quite up to scratch in the 1860s, it was put 1,807 feet east of where Congress wanted it to be.
