As of end of excavation 2019, context 1020 was recorded as covering the entire northern part of Trench A (see paragraph 5 for a more thorough description). Context 1020  was interpretated as  a subsurface or an older ground horizon, possibly humanly altered in connection with the construction of stone constructions in the area. It is hypothesized that 1020 continues southwards in the middle part of the trench and hence is covered by stratigraphy not yet excavated in that area. 

One square meter of 1020 was excavated in the northern part of the trench in order to gauge its depth and possible function.  At a depth of 0,20 to 0,25 m context 1020 gradually transitioned into a lower context (1035). This context was interpreted as a lower leveling layer or natural subsurface with infiltration.
