Are Tribal passes needed on the Cino route?

[Mark Davison]

I'm planning a bike tour for late July and part of the tour runs from Hot Springs MT to Kalispell. I would like to use the route from Day 2 of Cino to stay off the highway. The question is: since this is on tribal land and off of the highway, will tribal passes be required, and if so, which one(s). Bicycling is not specifically listed as an activity requiring a pass, but I'm assuming a pass is required.
