I don't think it is the Zone, as I can't see it at Lone Pine Lake. You will need to select "Terrain".

Wagga, I think that's just a 3D shading effect you're referring to. The steep eastern escarpment shows up as darker because the light source used to render the topography is coming from the west. That would explain why it only shows up in terrain view. In some 3D mapping programs you can change the direction of the lighting.
