As noted by David Rumsey:
Shows route of Pony Express with names and location of relay stations. Includes text by Howard R. Driggs, and color vignettes of Court House Rock, Chimney Rock, Old Fort Kearny, Buffalo in the Valley of the Platte, Old Fort Laramie, Relay station near Utah Desert, Sacramento - passing Old Fort Sutter, etc. '
Route covers 1,600 miles with total of 190 stations every twenty miles from California, Nevada, Utah, Wyoming, Colorado, Nebraska, Kansas and Missouri. Each of these stations was staffed and equipped to provide a fresh horse for each of the eighty riders who made a 120-mile ride before handing the mail off to the next man. In this manner, the mail could be delivered between St. Joseph, Missouri, across the Great Plains, over the Rocky Mountains and the Sierra Nevada to Sacramento, California, in just 10 days.
