Searching about at the App Store and found a terrific "Free" app called Topographic Maps of Canada. I downloaded it and it quickly adds tiles to it's database that work even when you are offline. Maps are true Topo and the refresh is amazingly fast. Haven't used it in the field, but it could be very handy as it shows all things Topo. (Creeks, streams, elevation etc -) Might help save a nasty bushwhack when a more circuitous but less nasty route to a cache is available. Anyway - it's free and fast! Inkyfiller
