1. Twin Sisters Marker
Of all of the wonders at the City of Rocks, the two peaks in front of you, called the Twin Sisters, stirred the greatest interest among passing emigrants. Many mentioned them in journals. Some sketched them, and in later years photographed them. After months crossing monotonous prairie to the east, the travelers found the Twin Sisters - sights to behold.
But while most emigrants saw the Twin Sisters as scenic wonders, few, if any, knew that they were geologic wonders as well. Though the "twins" look nearly identical, they are vastly different geologic formations, consisting of rocks formed many millions of years apart.
Erected by National Park Service, Idaho Department of Parks and Recreation.
