Zé is contemplating ascending the south ridge of Hastings Peak so I took some pictures. I really couldn't tell if there was or wasn't a use/game trail but the pictures do give a pretty good idea of how steep this ridge would be. It certainly would not be the fastest way to the top!
Kept my eye out for a solo hiker with short, spiky hair and an orange pack (Liz!), but saw no such person. A pair of hikers that made it to the toll road indicated that there were a lot of rock slides on the road. Not sure what that meant (impassable? annoying? etc.) but they turned around having no plans to go on to Mt. Wilson due to the snow up higher.

Notch in south ridge of Hastings...

Looking down south ridge from just below summit (can you see my house?)...

Helicopter heading towards the city. Came from somewhere to the north but east of Mt. Wilson...

More pics.
