It’s really an interesting drive through Eastern Oregon/Southern Idaho toward Wyoming. It’s a volcano natural museum. Just don’t take the drive in the winter!
I need to do some wondering in that direction.
We have been in Yellowstone more than a dozen times and now go annually again since we retired and bought a 5th wheel RV.
If the caldera blows I would just as soon be there.
Today I drove (again) on the highway between East Wenatchee, and Quincy, WA in the deep gorge created by the Columbia River. The north side of this river valley displays an incredible continuous cliff of multiple layers of volcanic eruptions over the millennia. Right next to the highway. If you are interested in geology, (I am) this drive is spectacular. Central WA State is loaded with these kinds of geological marvels.
