If the red arrow in the gif is actually the lower west edge of the concrete structure,
That white is too low to be the top of the concrete base, though it MIGHT be part of its edge:
However, looking at this gif, two things strike me:
1. Does the white edge marked by the green arrow (but seen so much better in the above gif) correspond to either the the light-blue or orange arrow-------------i.e. is it the right (east) edge of one of the two white columns over on the west side?
2. This landmark is surely a useful reference in plotting Mr. Bell's POV
The map suggests that it and its counterpart to the east are bracketing the doorway almost perfectly
In which case, the doorway behind the foliage goes substantially farther west than we've been giving it credit for.............
