In the heart of southern Idaho’s high desert, archaic monoliths defiantly rise from the earth against a backdrop of azure skies and wild grassy plains. This mesmerizing spectacle is none other than the City Of Rocks National Reserve; aptly dubbed as ‘The Silent City.’ Located near Boise, it spans over 14,407 acres packed with geological wonders that date back millions of years.
This reserve stands apart not just due to its abundance of towering granite pillars but also because of what it represents - a living testament to our planet’s dynamic geological past.

Geological Heritage: Carved By Time
A glimpse into the formation process of this geological marvel takes us 28 million years back when violent volcanic eruptions occurred beneath an ancient shallow sea that covered Idaho. Over millions of years, erosion sculpted the hardened lava into peculiar shapes resulting in clusters of rocky spires that dominate today’s landscape.
During the Gold Rush era around 1843-1882, more than 200,000 emigrants etched the history of their epic journey in axle grease and stone on Register Rock, one of the prominent features within the Reserve. As a testament to this historical significance, the reserve was declared a United States National Historic Landmark in 1964.
