IceCyclesmodelled ice formation

This estimates whether ice has FORMED. It says nothing about ice QUALITY, bonding, or whether a route should be climbed.

Modelled from weather data. Not an observation of ice, and not advice.

Jackson Falls (Shawnee), IL

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. None has a confirmed position, so they are listed here without a model estimate.

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.
