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?

The two main ones are about five miles long each.
After getting to the top of the one in Butte area, the down grade is nearly as bad. Watch your brakes and use compression brake if equipped.
