Before you book
This bet missed 0 of the last 10.
None of the last 10 came in under 8″ — a bust, under a third of the bet.
Odds count natural snowfall only. At snowmaking-dependent resorts, early-season cover can be fine in a low-natural-snow year.
The season, window by window
The bet: 12″ of new snow per week, scaled to each window. Counted from real seasons — how our odds work.

Field notes
Boulder's backyard hill — tight, wind-affected, and smaller-feeling than its acreage, but the Corona Bowl steeps and West Ridge trees are real terrain when filled in. A locals' mountain, not a destination.
Mostly relevant when Front Range logistics keep you near Boulder. Wind holds are chronic. The Divide options forty minutes west usually win unless convenience dictates.

These are historical odds from the last 20 winters — not a forecast. Inside 16 days of a trip, a forecast is the better instrument; beyond that, counting real seasons is the honest play. Every number on this page is quoted under methodology v1.2.0, the same math we grade ourselves against in public.
