Fort Kearny was an old post in Nebraska. It is now a thriving town and the capital of the county of the same name. The trail from this point led westward for 200 miles along the Platte River to Julesburg, in the northeastern corner of Colorado, then to Fort Laramie, whose gray ruins stand to-day in southeastern Wyoming, fifty miles west of Cheyenne. Next, over the foothills to the northwest, and through the famous South Pass of the Rocky Mountains, by Fort Bridger to Salt Lake City.
