Description

Register Rock is a historic site where many Oregon Trail emigrants carved their names on a large. It is located along Rock Creek and near the Snake River, roughly southwest of American Falls along the former routing of U.S. Route 30 and near Interstate 86. The rock is located in what is now Massacre Rocks State Park and is protected by a shelter. It is also near a segment of the Oregon Trail Historic District.
Also at the site, roughly west of Register Rock, is another much smaller boulder upon which a 7-year-old boy by the name of J.J. Hansen carved an Indian head and preacher head. His original work was completed as he was traveling along the Oregon Trail to Portland with his parents in 1866. Over forty years later, in 1908, he returned to the site and dated the original work.
The site was added to the National Register of Historic Places on July 24, 1978.
