Narrative:
I went over the mountains at 4000 ft and called on radio direction of flight. The other planes were at 4000 ft sightseeing so I started to drop and head straight for the river and called again direction of flight and altitude. I was only one in plane and dropping down I looked out r- hand window, saw a beaver off r-hand wing and it was gone before any action could be taken. The beaver pilot called and said someone went in front of him and I called and said I called my flight path. He was behind a mountain and may not have heard the call. The beaver was climbing and I was descending. I am not going into mountains again when they are sightseeing and will follow river then.

Narrative: I WENT OVER THE MOUNTAINS AT 4000 FT AND CALLED ON RADIO DIRECTION OF FLT. THE OTHER PLANES WERE AT 4000 FT SIGHTSEEING SO I STARTED TO DROP AND HEAD STRAIGHT FOR THE RIVER AND CALLED AGAIN DIRECTION OF FLT AND ALT. I WAS ONLY ONE IN PLANE AND DROPPING DOWN I LOOKED OUT R- HAND WINDOW, SAW A BEAVER OFF R-HAND WING AND IT WAS GONE BEFORE ANY ACTION COULD BE TAKEN. THE BEAVER PLT CALLED AND SAID SOMEONE WENT IN FRONT OF HIM AND I CALLED AND SAID I CALLED MY FLT PATH. HE WAS BEHIND A MOUNTAIN AND MAY NOT HAVE HEARD THE CALL. THE BEAVER WAS CLBING AND I WAS DSNDING. I AM NOT GOING INTO MOUNTAINS AGAIN WHEN THEY ARE SIGHTSEEING AND WILL FOLLOW RIVER THEN.
