As we returned from a hike this afternoon, Papa and I heard an engine running and realized it was a helicopter flying low over the mountains. I got my camera and followed the helicopter for about 10 minutes, as it circled around the mountain and flew to a spot on the ridge. The doors were open on both sides. The chopper hovered close to the ground, on the ridge, for about 5 minutes, then slowly flew north along Bald Ridge and out of sight.
