Hey guys - for those of you with iOS devices, this is a simple (and free) app that includes topographic info for at least most of Southern Ontario (and a good chunk of the rest of Canada from what I've seen). Should be very handy for exploring new streams which can be difficult to locate on Google and Apple Maps.
