Down through the snowpack
Dev digs the study pit beside the lodge before the meeting and reads it top to bottom. The new snow sits on Tuesday night's, and a thin crust from the late-January warm spell decides which slopes open first.
The bars show how hard each layer is. Dev pushes a fist, a finger, a pencil or a knife into the wall, and the harder the snow, the smaller the thing that goes in. A hard layer under soft snow is what the guides watch.

0 to 40 cm · Soft (a fist goes in)
Light, cold, bonding to itself. Reading now
Tuesday night's snow, wind-pressed on the ridges

The first laps go where the wind did not load it.
A thin crust from the late-January warm spell
55 to 57 cm · Very hard (only a knife goes in)
Tracked by hand in the pit.
The settled base, built since December
57 to 260 cm · Hard (only a pencil goes in)

Day one adds beacon practice, where you learn the avalanche transceiver you carry all week, and a confirmation run. On it the guides check that everyone is in the right cat.
For whoever worries about you
If someone you love is coming to ski with us, this part is for you. Every morning starts at 5:45 with the guides reading the new snow, the wind and the temperatures. They choose the day's runs from what they read.
Every guest carries an avalanche transceiver, a probe, a shovel and an airbag pack, and practises with them on day one. Each cat goes out with two guides who hold current professional certification, and the 5:45 meeting closes with a radio check.
We manage avalanche risk every morning, and we can't remove it. If you'd like to learn how avalanche risk works, these two public sources teach it well.
