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?

Also heard there is a long stretch with no services, is that the case?That's a question of what constitutes a "long" stretch, and how much services you need.
It's an interstate highway, so there are services at very frequent intervals. But it's certainly not urban. A quick perusal of your Rand McNally or Googlymaps will show you.
