Been a while since I've been up that way, but I don't remember Halibut being
that big a thing in Valdez or Whittier, but Homer that's a different thing.
There should be some Kings in the mix at the same time. The run into
Whittier has lots of glaciers on it, but with the global warming lately I
don't know how much you'll see in the water, hear the glaciers that used to
be in the water when I lived up there 25 years ago are now quite a ways up
the valleys. Anyway where Kachemak Bay enters Cook Inlet is a hotspot, Homer
is almost on top of it. I imagine the Glacier Bay runs and the one out of
Yakatat would be the most productive if you want to get close and personal
with a glacier. The run into Haines and Skagway is far prettier than Valdez
or Whittier. Lynn Canal is a fjord with waterfalls going into it all over
the place.
