Onward from Fort Kearny the white-hooded prairie schooners crawled like an army of gigantic ants along the south bank of the Platte. The Forty-niners were awed by the vast emptiness of the treeless plains, the endless horizon, the shimmering haze, and the sudden, drenching thunderstorms. Pushing beyond the forks of the Platte, they followed the margin of the South Platte to near the present town of Ogallala, Nebr. Here, at what was called Lower California Crossing, they ferried or swam the river amid scenes of shouting confusion, then headed for the North Platte. Hundreds of extant emigrant journals vividly describe the classic trunk route of the Oregon-California Trail up the North Platte. From the plateau the trail descended rather abruptly via steep Windlass Hill down Ash Hollow (near Lewellyn) to the river. Hugging the south bank, the trail passed many curious hills and formations which afforded welcome relief from the monotonous scenery. Courthouse and Jail Rocks near present Bridgeport, Chimney Rock near Bayard, and Scotts Bluff were among the most notable of these landmarks, which so frequently aroused poetic fancies and rapturous descriptions in emigrant journals. At Scotts Bluff in 1849 the trail made a wide detour, south of the present monument, up Gering Valley, and over Robidoux Pass, then northwest to regain the Platte near the mouth of Horse Creek. Sixty miles beyond the bluff the Forty-niners came to historic adobe-walled Fort Laramie (Fort John of the American Fur Company), which was in the very process of being purchased by the United States Army. The Stars and Stripes were hauled up at the fort on June 26, and the army immediately began the construction of new buildings. Pausing here only briefly to rest and obtain provisions, the emigrants continued west and north via the North Platte and the Sweetwater toward the Continental Divide, guided by such landmarks as Laramie Peak, Red Butte, Independence Rock, Devil’s Gate, and Split Rock. Just beyond broad, barren South Pass, flanked by the snow-covered Wind River Mountains, the Forty-niners reached the edge of the Pacific drainage. They still had a grueling journey over mountain and desert before they would reach the end of their rainbow.

Oregon travelers were families, seeking farms; most of the California emigrants were young men, unmarried or unaccompanied by wives, who were seeking a quick fortune. Young women who did make the hazardous journey were besieged with suitors. There were weddings and honeymoons on the trail. There are also records of gold rush babies born in wagon beds.
