Malibu Creek State Park: M*A*S*H (1972) this screen grab is from the pilot episode opening sequence. I took the bottom 2 photos in 2018 during a trip to LA. There isn’t much there anymore except a couple rusted out hulks of vehicles and a sitting area to indicate the mess tent. The 30-45 min hike was definitely worth it. Finding this location was the highlight of our trip. 34°05’47″N 118°44’41″W
