The emigrants inscribed their names on a variety of "register rocks" all along the trails. These signatures served a number of purposes. Many emigrants inscribed their names for the simple purpose of declaring, to one and all, that they had made the trek. Others hoped their signatures would signal to family and friends behind them on the trail the date at which they had reached this point. Today, these signatures can still be found at a variety of trail locations. Register Cliff is one of the best remaining signature rocks on the trail.  It lies adjacent to an emigrant campground about one day’s trek west of Fort Laramie. Its soft sandstone continues to invite visitors to inscribe their names. Although a prominent visitor site today, no contemporaneous emigrant document has yet been found which references Register Cliff. Sandstone cliffs to the east and west of Register Cliff also contain many well-preserved emigrant signatures. The trail is visible a few yards below the cliff.
