The imposing rock formation of Scotts Bluff National Monument in Nebraska rises 800 feet above the North Platte River and the surrounding prairie. For pioneers and travellers, it was visible for several days before they actually reached it and meant the end of the Great Plains and the beginning of the Rocky Mountains. Visitors today can get a sense of frontier time as they look out over some of the the best preserved prairie in the country – gorgeous grasslands relatively untouched by human disturbance.
