Before you book
This bet missed 8 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
Jasper's quiet giant — real vertical, empty alpine bowls, and a long high-speed quad accessing terrain that would draw crowds anywhere less remote. The solitude is the luxury.
The remoteness is total: hours from Edmonton, further from Calgary via the spectacular Icefields Parkway. Jasper town is low-key charming. It only fits an ambitious Alberta road trip — but it rewards one.

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.
