When it comes to map packs, in the digital age, the consumers are fortunate enough to have a lot of variety. I've used some Fiery Dragon and some Skeleton Key Games before. The only bad thing about such maps, and it's true of this one as well, is they can be ink intensive.
The good news here is that the map comes in two formats, one full color and one in black and white.
For me, I instantly thought of a certain old warhammer adventure that is on a river. Rivers are a popular place for 'dramatic' turning points. They're often a huge part of historical battles acting as a barrier or waiting until it's low enough to cross or knowing of a crossing.
The art on these is top notch and if this specific map is one you're looking for, it's well worth getting. The fact that it's scaled for 1" per grid makes it easy to use with Pathfinder or other games that use "each square equal 5'.
