Snow station

The base and the outlook for this route come from the Tinkham Creek station, 143 ft below the trailhead. A station below the trailhead reads low and melts out early, so the snow here is usually deeper and lasts longer.

The place

Before you go

The forecast and score here cover snow, sun and rain at the lot and on the snowfield above it. They leave out avalanche hazard, wind, finding your way in cloud, and whether the road is open. Check the avalanche forecast and the road status before you go.
