Crossing the Rockies in the North?

[laminico]

Hey ! I am riding across America... got to Iowa City so far and I am wondering which route would be best to cross the Rockies. As I am heading to San Francisco, I do not want to take a route that is too north (as suggested by one of the ACA maps). Yet the south route thru Colorado and Nevada should be too hot.

I am therefore looking for advice for a route across Wyoming, Idaho and Oregon (then I make a left towards San Francisco). Thx !
