Probably don't need:
- Snowshoes
- Avalanche gear (metal shovel, probe, beacon)

Elevation gain is about 3300 ft.

We'll be going up the open NE ridge, not the more common NW ridge through trees. I've done this route a few times and it's fun, and even if we don't summit the views are great.

We'll only do this trip if the avalanche conditions are safe and if the weather forecasts are friendly (friendly = no storms, no high winds, and no single-digit temps). If the trip is canceled then there won't be an alternate destination.

When to meet:
Sat 7am (we'll leave the cars and start hiking then)
Where to meet:
Annette Lake TH, elev 1920 ft
I-90 exit 47 then 0.5 mi SE to the TH
Lat/Long = 47.392915, -121.474159
35+ minutes from I-90/I-405 intersection
