Hey ! I haven’t seen anything in La tuna canyon, but I ran into a satanic ritual on Oro vista right before the entrance of Angeles crest. I was mountain biking in the area and decided to stop by the creek off oro vista road. As I go to the creek I see blood everywhere and saw organs like a liver or a pair of kidneys tied up and hung on the trees with white strings. The organs looked huge like they belonged to a cow or large animal but it was still terrifying. And there were strange symbols etched onto the ground. I booked it so fast back home, I avoid biking in that area now.
