The hyper-real 3D trail map of Sierra-at-Tahoe

The real mountain, from 1-metre lidar: every run and lift (44 runs, 13 lifts), the forest tree by tree, the village, and avalanche slope angles.

• Pick any run, see it on the mountain, then drop in
• Ask the way anywhere, drawn on the snow
• Plan your days around the sun, then pre-ride them
• Find the cafés, bars, rentals and lodges in the village
