Many travelers on the Oregon-California Trail recorded good relations with Native Americans, who helped by delivering letters, pulling wagons up steep banks, teaching about edible plants, and keeping watch at night. Many travelers were fascinated by the native peoples, and Lodisa Fizzell wrote in 1852 of seeing several men she identified as Sacs and Fox, including a chief dressed in what she called real Indian style, with his hair shaved except for the crown lock and ornamented with beads and feathers. At times, however, conflict arose between Native populations and travelers as buffalo were scared away, the prairie was overgrazed, the small quantity of timber was exhausted, and water resources were limited. More Native Americans were killed by travelers on the trail than travelers were killed by Native Americans, and Native Americans were more threatened by disease than by guns.
