Maps and brochures
You must purchase the proper topographic maps before arriving.Route planning is easiest with 1:250,000 maps but you should navigate with the appropriate 1:50,000 maps. Use the Canada Map Office on-line search tools for finding topographical map coverage. The map office does not sell maps but can provide a list of map distributors and further information about maps.
Maps that you receive are up-to-date only to the year indicated on the map. Care must be taken when using topographic maps to prevent unnecessary accidents.
Sirmilik National Park lies within the area of compass unreliability. GPS receivers are your best bet for navigation. Keep in mind that batteries must be kept warm and even the best unit can fail. Bring a backup unit and the right maps.
