South of Eureka I took the Whitefish Divide Road. Don't have to take the exact same choices I did but along this general route there is are a good set of alternating choices.
In 2019 I took mostly US 93 from Eureka to Whitefish. Still not sure how I survived all the close passes. Going to the Sun had opened. I think that had something to do with traffic levels as it was not as bad in 2017, when GTS was still mostly closed.
