Unless i misunderstood the original post, he is saying the flat spot in question is something of a "bridge" between one ridge and another. That having been said, they will use the flat spot as you describe above(I call them saddles) to get from one side of a ridge to the other as opposed to walking up and over or out to the end and around. After years of hunting steep "hills and hollows" habitat, it is my experience thatyou can count on deer using certain terrain features for ease of travel without fail. To the point where if I'm looking at a brand new spot that is steep hills and hollows, I'll pick a spot based solely on certain terrain features.
