Not a piste. Neither marked, nor patrolled, nor secured: transceiver, shovel, probe, the day’s avalanche bulletin and, better still, a guide. Ski grade (1.1–5.6) = steepness and commitment; exposure (E1–E4) = consequence of a fall.

Before you go. A grade is not a guarantee: it describes the route in normal conditions, not on the day you ski it.
Check the avalanche bulletin for the range, carry a transceiver,
shovel and probe, and tell someone where you are going.
