Why Kayakers Use Topographic Maps
Maps can inform the "amphibious" kayaker with details on shore, as well the contours of the body of water you are paddling in. You will be able to find potential camping spots, landings, fresh water sources, put ins, take outs, and locate both public and private lands.
The problem has always been to find these topo maps for your area. (There are more maps than you can even imagine.) Then you must piece together the assortment of maps. Invariably your kayak or hiking trip will skirt the borders of several maps. Then you have to figure out how to bring and used three or four large paper maps while seated in the cockpit of your kayak.
NOW WHAT: For use in the field, you could put your waterproof
map in a large zip lock bag or see through chart case. What? It's waterproof!
Well yes - but this will keep your map at is best no matter what.
I have found that you should not dry the map while folded, it will stick.
Thoroughly dry the map before folding, or let air dry unfolded. These
maps hold up very well without a case, can be handled somewhat ruffly
in the field.
