Mount Lemmon (Santa Catalinas), AZ
The model estimates whether ice has formed. Ice quality and bonding are not observable from weather data and are not modelled. How the model works.
1 route across 1 area, every one with a confirmed position.
Ice watch
Ice watches run November to April.
Ice here is an event, not a season. A watch opens when a storm puts water on the rock and a hard freeze follows within the week, at this route's elevation. It is a rule of thumb, not a forecast that ice has formed, and it has not been validated: there are only about ten dated sightings in thirty years to check it against.
Access is yours to check
This site says nothing about whether you may reach or climb these routes. That is decided by whoever manages the land — a park, a forest, a city, a tribe, a private owner — and by permits, seasonal and wildlife closures and local law, all of which change. A route listed here is not a route you are allowed to climb, and a route with no restriction noted here may still be closed. Check with the land manager before you go.
