One technique you might find useful is to load EVERYTHING into a master map for Quetico ... maps, portages, campsites, fishing information, picto spots, waterfalls, etc.

Then, when you are getting ready for a trip, you can copy and paste the ones that are important for THAT trip and save it to another file.  Another reason for this might be to keep a record/log for each trip.  You can add more notations after the trip is over.  Some of these additions might even be uploaded from your GPS if you are using it for "note taking" during your trip.

And just to be clear, MK indicated that there are MAPS for Quetico.  You don't necessarily have to load ALL the maps for a given trip unless you are REALLY covering a lot of ground.
