Like the Elkhorn, the crossing of Loup Fork represented one of the early and very difficult river crossings during the trek west. All emigrants traveling west from Council Bluffs faced this obstacle. Latter-day Saints crossed at several locations along the Loup River before reaching the Platte River.

"At 5 a.m. the horn should be blown & every man then arise & pray, attend to their cattle, & have every thing done, in order that all may start by seven o'clock. That each extra man should travel on the off side of his team, with his gun loaded over his Shoulder; that each driver shall have his gun so placed that he can lay his hand on it in a moment, that every gun shall have a piece of leather over the nipple, or in the pan of his gun, having their caps, & Powder Flasks ready for a moment's warning.

"The Camp arose at the sound of the Horn, attended t their cattle, and observed it as a day of rest, for meditation, prayer & praise. All was harmony, peace, & love. . . . The brethren were called together to worship the Supreme, when President Young called on the choir to sing 'This land was once a garden place' followed by H.C. Kimball making prayer to our Heavenly Father; several of the brethren then spoke their feelings, & while G.A. Smith was relating the Prophet Joseph's instructions not to kill any of the animals or birds, or anything created by Almighty God that had life, for the sake of destroying it" (The Pioneer Camp of the Saints: The 1846 and 1847 Mormon Trail, Journal of Thomas Bullock, eg., Will Bagley , 124–125, 132).

“Travelled six miles and crossed the Loup Fork of the Platte at a New Ford discovered by Capt. Richards’ company a day or two previous, opposite to an old Pawnee village, Capt. Richards’ company having passed over the day before we arrived and was encamped on the opposite side of the river. Both Elder Benson’s comp. and [George] A. Smith’s were all safely got over together with the loose cattle and sheep the same day. In the evening we encamped near to Capt. Richards’ camp, where they had a ‘trip on the light fantastic toe.’”
