“Considered historically, the year 1858 is the beginning of the end of the picturesque extravaganza at the [North Platte] river crossing. First a prosaic military encampment, known as Mormon Ferry Post, appears in the picture. Then, in the winter of 1858-59, a bridge presents itself apologetically for our consideration. . . .
The first name, Mormon Ferry Post, was supplanted naturally enough by Platte Bridge Station; but its final appellation, Fort Caspar, was bestowed after the heroic death of Lieutenant Caspar Collins, and is the one which proudly comes down through history.”
[N.B. The Fort Caspar site is just to the south of the Pony Express Bikepacking Route and Mile 917]
