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.

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.

Cautions from the weather record

  • 7 consecutive nights above -1 C

    The model shows no overnight refreeze across this period. Modeled ice mass is being lost rather than rebuilt.

  • Peak modeled absorbed sunlight 147 W/m2

    This aspect takes direct sun during the climbing window at this date.

Formation weather at this face

Hours when the weather here would freeze water reaching the face — from sun on this aspect, wind, humidity and air temperature — and hours when it would not. This is weather, not a report of ice: whether water reached the face, and what formed, is for someone who goes to look.

Past 7 days

Mostly thawing

freezing 5 of 168 h · rain 20.5 mm · warmest 21 °C69 °F

Next 7 days, forecast

Mixed

Bar height: share of the day’s hours freezing. Lighter bars are forecast. A dot marks a day with rain.

Why this estimate is uncertain

Treat the amounts as rough. The formation weather above leans on fewer assumptions than the ice amount does.

  • route constants are not calibrated against observed formation dates
  • position is its wall's shared point; the wall faces one way throughout
  • position source recorded as wall_pin but not confirmed against the original
  • forecast lead of 0 d
  • horizon shading not traced; direct beam may be overestimated

Including if there was nothing there. A report of no ice is worth more to the model than a report of ice.

Sign-in exists so each person counts once per route per day, and so reports can be weighed against each other. There is no profile and no public score.
