As the boating season draws to an end, the next best thing to being there is to spend the hours looking at maps! This one of Franklin Island is from the Forest Management Planning for the Parry Sound area. Much of the province is subject to logging on Crown lands. Go to this website http://www.efmp.lrc.gov.on.ca/eFMP/home.do and follow the links to find maps of the area you are interested in. Each forest area is managed by a different company, and some of the maps are better than others. None of the maps are recommended for navigational purposes, of course!
The original map has a full legend, and better resolution. The little black dots are Rk, which means rock.
