An inlaid brass plaque marks the only point in the United States where four states meet: Arizona, New Mexico, Colorado, and Utah. Despite the Indian wares and booths selling greasy food, there's not much else to do here but pay a fee and stay long enough to snap a photo; you'll see many a twisted tourist trying to get an arm or a leg in each state. The monument is a 75-mile drive from Kayenta and is administered by the Navajo Nation Parks and Recreation Department.
