Tintina Trench — Stewart Crossing Geological Viewpoint

The Tintina Trench is a continental-scale strike-slip fault valley that runs for over 2,000 km across the Yukon and Alaska. At Stewart Crossing, where the Klondike Highway meets the Silver Trail (Hwy 11) junction, you get a proper view down into this geological feature — wide, flat-bottomed, and unmistakably formed by something bigger than erosion alone. The Stewart River moves through the floor of it here, and on a clear day the scale of the whole thing is genuinely impressive. Good staging point if you’re heading up to Mayo or Keno.

Pull off at the highway junction itself — there’s room for rigs and trailers. No facilities, no signage explaining the geology, but that’s what you’ve got field guides and campfire conversations for. Season runs May through September before the first snows make the Silver Trail sketchy.
