Just reading AIR DISASTER-the prop era, and 1 chapter is about this accident. It was Super Constellation N6902C Star of the Seine, and DC.7 N6324C Mainliner Vancouver, the Connie ended up approx. 1000ft above the Colorado river on a rocky shelf, the largest piece was the tail fin which ended upside down. The DC.7 was 2500ft up then fell into a deep gorge! no large pieces just burnt pieces, reports stated that parts were driven 20ft into the granite, and coins in a purse were fused together. It was in such a bad place to access they flew Swiss mountaineers in to help in reaching it.
