No trip report, but short videos.
Day 1: Etiwanda canyon up to Joe Elliott campground via canyon&Big tree trail
Day 2: to Mount Baldy notch via Cucamonga Peak trail
Day 3: to Blue ridge via Northern Backbone(side trip : Baldy)
Day 4: to Valyermo which was via Manzanita trail to Devils Punchbowl park and opposite direction desert foray to St.Abbeys via Pallet Creek.
Overall an impressive blend to ponder for any city/desert route. Etiwanda canyon was a personal choice(to finish his exploration of it).
And then to end it with a blazing hot desert walk.
Internet: South/North over 4 days(Etiwanda to Valyermo)
Just to make it clear, I have nothing to do with any of this...but if the guy was backpacking, it couldnt have been all that hard. I would think the main difficultly was being exhausted from scrambling Etiwanda canyon in the summer. I guess it looks like class 2.
