Mr. GG2 is from that area. He used to hike and camp there as a child. He spent so much time roaming those mountains that the LA Sheriff’s dept used to call on him as a tracker for missing persons from time to time. I think he was only 15 years old. He told me those mountains are really rough terrain.
They are.
I was hiking with my future BIL one time and almost made the same type of fall but he managed to grab hold of me.
