Yes they can! I laminated mine at staples. If it is a thick laminate (very plastic) I would recommend placing them under a stack of books after creasing them so that they stay flat and not open up. If a thin laminate is used, you shouldn't have to place them under any weight. It it much easier to use the passporter maps than the Park issued maps, and of course they will stay dry! Give it a try.
kwdietrich1 - Thanks for the info and advice! I have written all these little codes on the maps so I know what accomodations each has for my dad's hearing disability and I don't want them to smudge.
