Here the topography of the land forced all the wagons to use a narrow track over a rock rise. The years of wear are visible still. Ruts have been indelibly etched into the rock. You can walk the exact path of the wagons, envision the work it took to move a wagon weighing a ton or more up this rise.

Register Cliff was a resting place along the North Platte River. Wide grassy meadows offered feed and water for the stock. It was a chance to mean broken rigging, rest the animals and the people. While waiting, the limestone cliff adjacent to the meadow offered the opportunity to leave a marker of each persons passing. The unprotected areas continue to have names added of those who have come to remember the earlier travelers.
