See how steep the ground is before you're on it

Slope angle shading colours the ground by how steep it is. It uses the same colours backcountry and avalanche maps use, so it reads the way you already expect.

Steps

Open the layers sheet
Map tab → the layers icon in the left tool column.
Turn on slope angle
Switch on Slope Angle. The shading draws over whichever base map is active.
Read the legend
A legend appears at the bottom left with the angle bands. Colours mean nothing without it, which is why it is always shown.

Worth knowing

It works offline anywhere you have already downloaded the map.
This is terrain information, not an avalanche forecast. Check your regional avalanche centre before committing to anything steep.
