City of Rocks

National Reserve - Idaho

The City of Rocks National Reserve, also known as the Silent City of Rocks, is a United States National Reserve and state park lying 2 miles (3.2 km) north of the south central Idaho border with Utah. It is widely known for its excellent rock climbing and rock formations. The rock spires in the City of Rocks and adjacent Castle Rocks State Park are largely composed of granitic rock of the Oligocene Almo pluton and Archean Green Creek Complex. California Trail wagon trains of the 1840s and 1850s left the Raft River valley and traveled through the area and over Granite Pass into Nevada. Names or initials of emigrants written in axle grease are still visible on Register Rock. Ruts from wagon wheels also can be seen in some of the rocks.

[Site Under Development] large granite outcrops Wildland Fire in Douglas Fir: Western United States Douglas fir is widely distributed throughout the western United States, as well as southern British Columbia and northern Mexico. Douglas fir is able to survive without fire, its abundantly-produced seeds are lightweight and winged, allowing the wind to carry them to new locations where seedlings can be established. Close-up of Douglas fir bark and needles. Wildland Fire in Sagebrush Sagebrush will burn when the surrounding grasses are dry. With strong winds, fire spreads rapidly with flames sometimes reaching over 30 feet high. While fire easily kills sagebrush, the other plants resprout from protected roots producing lush forage for wildlife and livestock.
