I know you're water data is not yet ready, but how about some fjords?
Sognefjord in particular.
60.99 x 7.04 ... a shot at 2 meters altitude, facing more or less westward (I think that is the right direction, anyway), and another shot from higher altitude, looking down on it
Best thing I could come up with for a request that didn't include Lake Lewisville :p.
Oh, or perhaps Mount St Helen's? That might be interesting
