Large, linear cut running NE to SW across N part of Area E and continuing into Areas C and D to the W and past excavation limit in E. Currently interpreted as a possibly 17th cent. A.D. drainage channel. FIll 4001 in cut 4002 in Area E only partially excavated to depth of ~25cm to expose edges of cut and avoid contamination with earlier layers to S. Cut not photographed or shot in in 2011, but fill clear in 2010 and 2011 aerial photos.
