Matt has been very busy this last month with photographing the eagles that converge on Haines each fall. Here is an explanation from the American Bald Eagle Foundation (click

Why Is The Chilkat River So Special?
The natural phenomenon responsible for five miles of open water on the Chilkat River during freezing months is called the “alluvial fan reservoir”. This subterranean reservoir is a result of glacial activity ending 10,000 years ago which forces the water to percolate through coarse alluvial material creating friction which results in a warmer water surface temperature in an area that is, at times, five square miles. As a result, the water surface remains free of ice, thereby permitting the chum salmon to spawn late into the year. This salmon run is the last significant salmon spawning event in North America.
Five species of salmon spawn in these and other nearby streams and tributaries. The salmon runs begin in the summer and continue on through late fall or early winter. The salmon die shortly after spawning and it is their carcasses which provide large quantities of food for the eagles. This combination of open water and generous amounts of food bring large concentrations of eagles into the Chilkat Valley from early October through February, with the highest concentration being in November.
Here are the wonderful photos (I'll have to post them all over several nights as he is way ahead of me and I think the latest number that I heard was 500 gig's of photos!!!).
