Cutting through a wall with Color Key?

I am making a map which is a mountainous pass. Most of the map is cave wall. So I have the path coming from the southwest going north to an open area. Then there should be a path going to the northeast. So I used color key to cut out an area but instead of showing me what is below it is showing me a black area. Am I doing this right? What should I be doing
