You will need to have a Baltimore/Washington TAC to possibly answer this. Looking at the TAC near the 200 Radial of the Hagerstown VOR there is a magenta ellipse. I know that typically the thick magenta line means Class E to 700 AGL, but in this case I am confused. If you follow the Class E (to 700) airspace boundary (not the ellipse but the major boundary) around it is a continous boundary. Is this ellipse an exclusion and the small area inside class G? There is also one a little north of Quantico. Thanks in advance I am interested to hear an answer or at least a theory.

The small area inside has a Class E floor of 1200' AGL. The area outside has a Class E floor of 700' AGL. The small area inside is what is left over after the two Class E5 areas below are established:
AEA DC E5 Washington, DC
That airspace extending upward from 700 feet above the surface within an area bounded by a line beginning at lat. 38°55’19” N., long. 76°12’28”W., to lat. 38°27’18”N., long. 77°03’51”W., to lat. 38°36’30”N., long. 77°15’17”W., to lat. 38°35’12”N., long. 77°37’06”W., to lat. 38°57’17”N., long. 78°02’29”W., to lat. 39°30’00”N., long. 78°09’00”W., to lat. 39°44’36”N., long. 77°36’08”W., to lat. 39°43’28”N., long. 77°00’00”W., to lat. 39°36’08”N., long. 76°28’38”W., to lat. 39°19’38”N., long. 76°04’04”W., to the point of beginning excluding the airspace that coincides with the Aberdeen, MD, Hagerstown, MD, Winchester, VA, Midland, VA Class E airspace areas and P-56A, P-56B, P-73, P-40, R-4009, R-4001A, R-4001B, R-6608A, R-6608B and R-6608C when they are in effect.
