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.

Hickory Canyons Natural Area, owned by L-A-D Foundation, managed by MDC (https://mdc.mo.gov/discover-nature/places/hickory-canyons-natural-area). MDC Natural Areas rules: 'Climb. Rock climbing and rappelling are prohibited.' (https://mdc.mo.gov/discover-nature/places/natural-areas/natural-areas-visitor-guidelines). Ice is not named, but climbing here is effectively prohibited.

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.

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.
8 hours of modeled melting in the past 72 hours
Modeled loss of 13 mm water equivalent over that period.
13 C temperature swing in the past 24 hours
Rapid warming expands ice against the rock behind it. The model treats this as a bond stressor independently of whether melting occurred.
Peak modeled absorbed sunlight 331 W/m2
This aspect takes direct sun during the climbing window at this date.

No one has reported on this route in the past three weeks.

Add what you saw

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.
