elevation: 2524 m
aspect: 261.2°
position: map_digitized
terrain check: passed

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.
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 281 W/m2
This aspect takes direct sun during the climbing window at this date.
