About a two hour drive from Cache Valley. You'll find an awesome formation of rocks in southern Idaho named Castle Rock. Unfortunately this was the weekend the weather decided to drop from the 60F temperatures we've been having into to snow weather. Which pushed me down off the rocks in the area as it tends to make the slick rocks a bit dangerous to be on.
Definitely going to go back, for this formation as well as the nearby City of Rocks, once the weather has warmed up again.
