Chairlift

Runt Mountain is a SOTA peak at the top of the chairlift at Lookout Pass Ski area. Lookout Pass Ski area is on Interstate 90 at the Idaho/Montana border.

From Idaho, take exit 0 on Interstate 90 and turn right into the parking lot of the ski area. You will have to purchase a lift ticket ($13) for the ride up the main chair. I activated this in the summer as they open the area up to hikers and mountain bikers. You might be able to activate this in the winter but with much more difficulty with skiiers buzzing by you. 

Big Mountain is part of Whitefish Ski Area and in the summer you can take the chairlift to the top ($20) and hike, ride bikes and activate Big Mountain.  The communication towers that sit atop the summit are easy to see from the top of the chairlift and it's only a short quarter mile walk up the graded road to the top.
