This is probably the foundation trench of the north wall in the LGR:025 room
No clear border for the trench cut is visible, only the limits of the stones
(It might still be filling, then i this would be the remains of a very thick part of the insualtion layer)
This locus "only consists of stones" we took mesurements of 3 different stones.
7x9, 13x10, 16x10 - they all seem very similar in size.
