Ice Climbing — Formation Status

How Ice Formation Score Works: Ice quality depends on sustained sub-freezing temps. The meter tracks days below 32°F (formation) and sub-20°F (thick pillar building) against recent warm spells. Prime = 2+ weeks hard freeze with no thaw. Out = temps too warm for ice to hold.

Hyalite Canyon

Bozeman, MT · 6,800ft · WI2–WI6+

🔒 Off Season ⚠️ Avy: Moderate

Weather data unavailable

Classic lines: Mummy II WI4, Chouinard Falls WI4+, Puss in Boots WI4, Canary WI5, Unnamed WI6+, Steep Rhyme WI4

🛣️ Road: FR-62 plowed to Hyalite Reservoir winter weekends + holidays. Verify plowing schedule at gallatinvalleylandtrust.org before visiting. Unplowed sections: park and ski/skin in.

GNFAC AVALANCHE

Unable to fetch current GNFAC forecast. Check https://www.mtavalanche.com before entering avalanche terrain.

💡 Best ice forms after 2+ weeks of sustained sub-20°F temps. Warm spells (>35°F) degrade pillars rapidly.
