It's right above Ainger Lake, of course! You'll find it north of Bozeman in the Bridger Range off the Fairy Lake road.

In this short video, Evelo Pourlamontagne takes us for a ride to Ainger Lake and then for a climb up the Ainger Formation. Even if you're not a climber, the view is fantastic and could make for a nice ride when you want to get out of town.
