Two craft near Camp Misery ranger station one large triangular one small, very small, cone shaped.Before midnight last night we saw one large triangular craft with no lights a few hundred feet off the ground. It was moving slowly through the valley down towards Big Fork Montana. One small, tiny cone shape with a yellowish orange top and bright white bottom zigzaged over the radio towers above camp Misery. The small one seemed to be going in and out of the valleys up and down the side of the mountain and darting around the large triangular shaped craft. The large craft turned and started moving north over the mountains and we lost sight of both of them. No lights were ever seen on the large one. It was kind of a purplish black glow. No sound from either of them. The smaller one went into a cloud and it looked like small lightning the way cloud lightning looks and reminded me of those things globes you run your hand around and the electricity follows your fingers around the globe. The lightning made no noise. We heard a faint rumbling sound a little time later. And heard aircraft about 30 minutes afterwards. Gary took pictures but don't know if they will come out said he got a shot of both of them around the radio towers together and a closer one of the smaller one as it went in the clouds and of the lightning.
