Ironbender,

i do not know for the passport but i crossed last week to go to Haines with my passport expiring in August this year and i was able to go back to Canada. tue US didnt even bother...

to the OP:

for the meat what is important is no bones at all and of course no brain part or they will destroy it at the border. you may need like in Yukon an export permit for the meat, the skin and the tropy.

please do check with your outfitter as for now there is a lot of fires.

good luck.
