Much of the Great Plains became open range, hosting cattle ranching operations on public land without charge. In the spring and fall, ranchers held roundups where their cowboys branded new calves, treated animals and sorted the cattle for sale. Such ranching began in Texas and gradually moved northward. Cowboys drove Texas cattle north to railroad lines in the cities of Dodge City, Kansas and Ogallala, Nebraska; from there, cattle were shipped eastward. British investors financed many great ranches of the era. Overstocking of the range and the terrible Winter of 1886–87 resulted in a disaster, with many cattle starved and frozen to death. From then on, ranchers generally raised feed to ensure they could keep their cattle alive over winter.
