FWIW
...Assuming you won't be guided, but will be using either a transporter or a charter flight:
- Although all bets are off in the current environment (i.e. impact of covid on folks coming to Alaska), transporters tend to book up a season in advance. Now would be the time to make inquiries for 2021....and depending on any number of things, many transporters tend give preference to their prior clients.
- Alternatively, one can just charter a flight from ____ (some town) to _____ some unnamed lake. Probably less critical to arrange in advance, but less certainty of being in a productive area as well.
- For moose, "boat" use tends to hit extremes: boat on rivers that are within reach from the road system (i.e. Little Su from Los Anchorage) and count on luck and hunting during the week to find a moose, or take multi-day trips up the bigger rivers to get into the country.
....of course, my colleague has a cabin within an hour's C180 flight of Anchorage and he routinely has his choice of moose to shoot by just hanging out for a few days.
