Any high mountain passes through Montana/Idaho on I-90
Headed to South Dakota from Portland, OR along I-90, curious if there is any high mountain passes like on I-70 through Colorado?

remember you are crossing the Rockies, so yes there are some high passes
i figured that but the question was if they were the long hauls like on I-70 thru Colorado over Vail, Loveland and Berthod Passes
