In the winter of 1864, the Navajo were removed from their lands in Arizona and New Mexico and forced to walk 300 miles to a military outpost called Fort Sumner, where they were imprisoned. The march became known as "The Long Walk."
Four years later, they signed the Navajo Treaty of 1868 with the US government that allowed them to return to a small portion of their land.
The current Navajo reservation covers 25,000 miles across all four states. The Four Corners Monument, where tourists can stand in Arizona, Colorado, New Mexico, and Utah all at the same time, is run by Navajo Nation Parks and Recreation, which was established in 1957 by the Navajo Nation Tribal Council. Navajo artists sell jewelry, food, and hold demonstrations of their crafts in the visitor center.
