The Lakota (Sioux) people mark the 150th anniversary of the Fort Laramie peace treaty between the Sioux Nation and United States government with a 400-mile horse ride from Green Grass, South Dakota, to Fort Laramie, Wyoming, where the treaty was signed.
A group of Lakota horseback riders make their way across a snowy field on the second day of their Fort Laramie treaty ride on the Cheyenne River Reservation near Howes, South Dakota, U.S., April 15, 2018. When the treaty riders are on native reservations they can ride backcountry (on a path through a natural environment) but off the reservations they ride on roads. STEPHANIE KEITH/REUTERS
