Brian- I believe he had help on some of the filming. A bush plane would drop off supplies every 4-8 weeks, and I know his brother came up to visit at one point.
I was impressed with both his camera work and the quality of the film itself (clarity, color, etc.).

BTW, Brian- when is the lake survey page going to be back up and working? I was meaning to fill out a few surveys for various trips I took this summer, but I got terribly busy at the end of the summer and have stayed that way up until now.
