⚠️ Avalanche Advisory: Mountain IQ scores factor in avalanche danger from GNFAC, FAC, and WCMAC. High (4) or Extreme (5) danger reduces the IQ score. Always check your regional center before heading out. MT avy season runs roughly Nov–May but can extend into summer at high elevations.

⛰️ Avalanche data provided by Gallatin National Forest Avalanche Center (GNFAC) — mtavalanche.com

⚠️ Avalanche conditions are extremely dangerous and change rapidly. This data is for informational planning only — NOT a substitute for checking official avalanche forecasts, carrying proper avalanche safety equipment, or completing avalanche safety training. You assume all risk.

About Mountain IQ
Mountain IQ (0–100) rates trail conditions for hiking based on: surface conditions (40%), precipitation (30%), wind (15%), and temperature (15%). Avalanche danger at Level 4 or 5 further reduces the score. A score of 80+ means excellent conditions; below 35 means hazardous — turn around or go elsewhere.
