That's really useful! I've been looking for one of these for some time. I'd prefer it didn't show the caves hidden in the bushes, or label the cave entrances (some players might assume correctly, that the higher the letter, the tougher the cave). But those are easy enough things to change in photoshop.
I handed the Micheal Kormarck illo to the players at the keep as an in game artist's rendition of the valley. When they actually arieved at the area, I began describing it with Alien Geometries to put the chaos into the Caves of Chaos.
The painting is by no means an accurate depiction of the ravine. For one thing, it shows the ravine walls as being nearly vertical, whereas judging by the elevation lines on the map, it's a very gentle slope that can easily be walked (not climbed) up. Maybe that's a problem with the map--the text describes it as a ravine with steep walls.
Anyway, I've been looking for a player map of the ravine for some time, but even this map doesn't do it. Why are the caves labeled? Why can you see the cave mouths that should be obscured by shrubbery? Why is it on two pages? I have fiddled around with it in Photoshop to create an actual player map: [attached]http://i57.photobucket.com/albums/g226/G-X/CavesofChaosPlayerMap.jpg
Use it. Hand it to your players and have them map their progress.
I know the painting doesn't match the map, but I am going with it first. I can scatter the various lairs/cavern complexes over the much larger ravine.
The original map is far too small.
So I am just going to divvy up the caves across the larger (pictureed) ravine. That way more of them can connect...and go under each other as the should.
