The Gooding City of Rocks consists of a type of rock (tuff) created by an ancient volcanic ash-fall.
Freeze-thaw erosion processes create monoliths rising from the desert floor north of Gooding in the Mt. Bennett area. The eerie, wind-carved formations, called “hoodoos”, are frequently covered with bright green lichens.
The park is large, and one could explore it for hours. Look for rock arches, wildflowers, and a creek that runs through. Spring time brings vibrant colors, and late summer through winter will provide desert landscapes. Hikers, bikers, or horse riders can be found here.
