Formation ABDZ
I have selected Z for the triangle shape because it was unlikely to have been used for other mounds.
Mound A resampled 4X
The mound has a piece out of it like Pacman, these edges point to mounds E or Z, and B quite accurately. This is unlikely to occur by chance.
Mound B resampled 4X
This also has a piece out of it which may point to other mounds.
Mound D resampled 4X
The center of it appears clear as a good spot to measure from. Also there seems to be a ridge pointing towards A.
Z and E are resampled 4X.
Mound Z is analysed first and E later. Z is a triangle shape and the sides seem to point towards A and D.
The angles between mounds
The center letter is the vertex of the angle.
