Above all, a merry Christmas to all,
Not a lot of time at the moment, but I wanted to add some comments :
For the actual delimitation of T11 see the attached image
The progressive opening of the rifts, and more precisely of families of parallel rifts, as we can see better in the Sentinel2 images, shows not only the strong northward thrust printed on the SIS and T11 by the SWT, but also the resistance opposed, especially by T11, which gives precisely the extension of the rifts (of each rift) is very often done by opening the new parallel rifts.
This should quickly lead to important calvings that will cut T11 and thus eliminate any direct contact between T11 and the PIG. Only the small unnamed tributary, east of T11, will remain to make the joint between T11 and the PIG. In addition, the ice mélange to the west of this tributary should gradually calve.
I don't see how this small tributary, even with the help of T1, can last for years, and in the years to come we will have to expect the extension east of DZ (Damage Zone) until it connects to the existing DZ upstream (SuDZ).
