What do you call the area north of Spring Road around 14th Street?

This is something I was wondering the other day sitting on the roof of the Red Derby -- what's the area north of Spring Road around 14th Street called?

It depends on how you define Columbia Heights (and we've talked a lot about that, see our previous debates) but many people consider Columbia Heights's northern boundary to be Spring Road (which is the ward boundary, and so thus a good border) or a little farther up, like Quincy Street. But then what's above that?

Is it southern (or southwestern) Petworth? That usually seems to be farther north and east, though. Wikipedia would have that area as Petworth. To me it's a different character than Petworth -- and if you look at the history of that map (scroll down), it's changed a number of times and doesn't seem to be based on any official things (it says Census, but that's the basemap, and the Census as far as I know doesn't define neighborhoods.) To add to the confusion, many people say the Georgia Ave-Petworth Metro isn't in Petworth, or just at its very southern tip.

There's a neighborhood called 16th Street Heights, but the borders for that are pretty unclear too. Google seems to place it farther north, around Hamilton Street NW. I've even heard of a 14th Street Heights, but I've never heard anybody say that. And what, is 14th Street Heights one or two blocks wide, then it's 16th Street Heights? That seems strange.

Farther west there's Crestwood, which seems to be between about 16th and Rock Creek, with Piney Branch as the southern boundary and Colorado Avenue on the north. Does it goes that far east and south to cover the Red Derby and up to Upshur?

At 14th and Taylor there's the Twin Oaks Community Garden, and just down the street there's a big apartment complex called Twin Oaks -- maybe we should start calling it that? It has kind of a nice ring.

Some people even coined the GaP for around the Georgia Ave-Petworth Metro, but I think that's really dumb.

The maps sites are no help either -- Google, Bing and OpenStreetMap are unclear there.

What do you think it's called? I suppose you could even coin something silly like NoDerb (North of the Derby.)
