Flying into a Valley

I have an APM2 running ArduCopter v2.6 with Mission Planner V1.1.97.

 

I want to be able to flying my DJI FlameWheel 450 down into a valley in auto mode. The problem is that the only place to takeoff from is on the top of the hill. Since absolute altitude doesn't work for copters, how can I get my quad to descend below the takeoff altitude? Can I just put in a negative altitude for those waypoints?

 

Thanks for the help.

    If I'm on a hill that is 100m above a plain (0m) and I send my quad 80m above the top of the hill and then tell it to fly out into the plain will the quad be 80m above the plain or 180m above the plain?
