🪨 DID YOU KNOW? 🪨
Near American Falls sits Register Rock, a historic stop along the Oregon Trail where pioneers paused to rest during their journey west.
Many travelers carved their names and the dates of their passage into the large basalt boulders. Some of those original inscriptions can still be seen today, giving us a fascinating connection to the people who traveled through Southern Idaho more than 150 years ago.
Register Rock is now protected as part of Massacre Rocks State Park.
