Please help me with these "white~"?

Question

On TV, a man is travelling Manitoba, Canada, and he says
"We actually have got some essentials to buy. Maps, that is the first thing, ...(looking for a map which seems much more like a white and black postcard)White Mouth, White Water, White Dog."

Is there maps called "White Mouth, White Water, White Dog" in Canada??
I search internet but could not find any of these.

does any one know what these are?

Answer 1

It could be rivers or campsites or something like that..sorry unless I'd seen the show I'm not sure what happened on the show.
