Get a set of Dr. Scholl's flat insets and glue stick foil to the bottom to keep your feet warm unless you have insulated boots. Avoid slick soles for slipping on ice. Get a few chemical heat packs and wear layers, hat and gloves. If you are going to be outside a bit, add glove and sock liners. Might also consider a small keychain flashlite.
Used to work for an outfit involved in O&G up there but now just fly up to Alaska for fun and to get Mexican takeout at Pepe's in Barrow.
Get the BoA Alaska Card if you are flying Alaska.
