Driving the Dempster in Late Summer: What to Expect

I've driven the [Dempster Highway](/dempster-highway) in every season except deep winter, and late August into September is consistently my favourite window. The light is different, the colours are starting, the road is in good shape after a summer of maintenance, and the number of other vehicles drops noticeably after Labour Day. Here's what you're actually getting into. ### The Colours The tundra colour change on the Dempster begins in mid-August and peaks somewhere between mid-September and early October depending on the year and elevation. The high-elevation tundra above treeline in the Tombstone area turns first — the bearberry goes red, the dwarf birch goes gold, the willow yellows. By September, the open tundra in Tombstone Territorial Park is a patchwork of gold, red, and orange against the grey granite of the mountains. This is genuinely extraordinary. It's the kind of thing that stops you on the side of the road with a camera or just standing there looking at it. Lower elevations and the boreal forest sections turn later — by late September. The entire highway corridor is typically in colour by mid-September. ### The Light Late summer light at northern latitudes is different from summer light. The sun is lower in the sky. The angle is more oblique. Shadows are longer and more dramatic, and the golden-hour light that photographers seek lasts much longer than it does in the south. If you're driving the Tombstone section in late afternoon in September, the light on the mountains is exceptional. You also get actual darkness again. From mid-June to mid-August, the nights in Dawson City barely get dark. By September, you have real dark — which means you can see the northern lights. The aurora season starts around the equinox, and September evenings on the Dempster, clear skied and dark, with the tundra visible in the foreground, is one of the better northern lights settings I know. ### Road Conditions The Dempster is a gravel highway and road conditions vary with weather and recent maintenance. By late August, the summer's worth of grading and patching is done. The road is typically in reasonable shape. Rain changes this quickly. A sustained wet period makes sections slippery and can slow your travel significantly. Check the Yukon government road report before you start. You still need two full-size spare tires. Late summer doesn't change the tire situation. ### What's Open Eagle Plains Hotel and gas station (km 363) operates year-round. The Tombstone Territorial Park interpretive centre is open through early September — check Yukon Parks for the exact closing date in your year. Inuvik services are available year-round. ### The Ferry Crossings The Peel River and Mackenzie River ferry crossings operate through late fall freeze-up, typically into October or November. In late August and September you have no concerns about the ferries. By late October, start watching the Yukon road report for ferry status.
