Well, I got a reply from the retailer and this is what he told me about the new W A Fisher maps...
"This year W A Fisher made the decision to change the aesthetic of their maps. ... sometime this spring they started shipping us these newly updated maps... which have more bold colors than the previous versions. (I deleted sections that would indicate the retailer.)
On some of these maps, I think the coloring makes sense and enhances readability (see attached image of map F-17). Here, they have used yellow for USA/BW, Dark Orange/Red for Quetico/CN, and lighten the Quetico side so that only the area right on the border is dark, getting lighter as you go inland. When PMAs are present, they highlight those in green to clearly differentiate the boundaries.
According to Fisher when [we]
reached out to inquire, they did this to differentiate the border. Previously, both Quetico and BW were yellow and the border was not bold enough to easily differentiate, ....
Long story short, it’s not an error, but an intentional choice by Fisher and the scheme they will pursue moving forward."
That's unfortunate in my opinion. I think the new coloring scheme is much more difficult to read, especially the blue on dark orange in Quetico, and was unnecessary. If some people were having trouble seeing the boundaries, they perhaps need to refine their map reading skills. That's assuming that these maps, although "not for navigation", do get used that way by many canoeists. I think the yellow backing color scheme is a good one for that reason. It's too bad because they're otherwise great maps. But that's my opinion and I'm not selling maps, so it goes.
As an alternative, these
GoTrekkers topographic maps look promising and come in 1/50,000 = 2.0 cm/km (1.27 in/mi) scale water resistant maps. It means I'll have to add campsite and portage information and that was the main reason I purchased the W A Fisher maps. The other thing I like about the Fisher maps is the scale being 1/42,240 = 1.5 in/mi (2.37 cm/km), which, except for the new color scheme, makes it a bit easier to see small details. But for me, being able to easily see water features on the GoTrekkers NRCAN maps overrides the scaling advantage of the Fisher maps.
