Retaining walls on an alignment corresponding to that of the basalt road in Area E (SU 4010). Associated with the North-South retaining wall (4011), but set at a different angle to follow the road curving to the east. The tangental retaining wall likely continued to the Southeast with the road, but many have been truncated by robbing activity. The two small filler stones (2263) seem to have been set in the gap of the two retaining walls (4011 and 2262). It appears that the foundation activity for 2262 cut wall 2353.
