There is only one place in the United states where four states come together at one point. That place occurs in the Southwest where Utah, Arizona, Colorado and New Mexico share a similar corner. They have built a monument called the Four Corners Monument.
I have traveled to the Four Corners monument and have photographed my kids playing on the monument. It is the only place in the nation where a person can be in four states at the same time and my kids had fun using their hands and feet to accomplish that very thing.
The unique landmark is on Navajo Nation land and is open for visits from the public.
