Where are you planning to arrive in Alaska? Knowing that will make it easier to give advice. I'll check back.
at least knowing where you're going makes help to give advice. "(perhaps) travel around and see the sites and wilderness before I get settled in". you might keep in mind a pearl from John McPhee's book Coming Into The Country. most work is seasonal. most seasonal workers don't much of a chance to go out and see the sights. actually, arriving June 8 means you get a late start on a summer job. not knowing if you're arriving with a skilled journeyman or with a large sum of money, i'll assume you're like the rest us when we got here. no skill, no place and no money. there's a few hostels in downtown Anchorage (which is quite a large city,btw) which allow extended dorm room stays - as long as you can pay. as far as Fishing Industry goes, best to immediately go to the Job Service in MidTown and take the little class they put on for anyone interested in going out to work in a cannery (a few hours). that's getting on at the bottom rung -long hours, slimey work, but food & board covered if remote. there's probably tourism jobs around Anchorage available, but expect them to dry up by the end of August- which is why you'll see 'termination dust' on the mountains behind town. Anchorage has a typical big city bus system- enough to get by. perhaps start looking at Craigslist to get an idea of vehicle and rent prices. not cheap. Kodiak, Valdez, Seward, and perhaps Wrangell (in Southeast AK) might be places you could gypsy camp while maybe getting on at a cannery and/or walking the docks looking for a job on a seiner ("salmon boat"). if you want to stay in Alaska, better do lots of homework and hit the ground running before things dry up at the end of summer. good luck and welcome to the Great Land.
