What was the long walk of the 1900?

The Long Walk was in 1864. 53 groups of Navajo people were forced to walk the 450 miles between August 1864 and the end of 1866. The Navajo people were held by the US Army in Bosque Redondo until they were allowed to return back to their lands in June 18, 1868. I have never heard of a Long walk of 1900.
