Winteregg
The left wall has overlapping rock that requires good technique. The powerful routes on the right side are steep and strenuous. It can get hot here as all of the routes are in the sun until 3pm. With this said, the south facing rock dries fast after a thunderstorm and may even be climbed on during mild winter days, except December and January due to lack of sun.
