Gradual natural accumulation of sediment from roughly Early Byzantine period onward that contains much residual earlier material and very sparse material representing activity in area during Modern era. Relatively shallow depth of this deposit spanning several centuries presumably reflects ongoing impact of sheet erosion that has removed sediment over sea cliff. Uppermost level thoroughly intermingled with contents of World War II ditch cut through area so that it is impossible to distinguish topsoil from mid-20th-century fill. Cf. Stratum B4.
Chronology comment
Recent and ongoing formation with much residue of all periods.
Explanation of deposition
Top level of widespread colluvium across southeast ridge including modern ground.
Soil matrix
Heterogeneous but predominantly pale-light brown (10–7.5YR 6/3), mostly loose, fine silt to sandy silt with sparse pebbles to small gravel (<4 cm range); distinct concentration of large cobbles (10-18 cm range) to south (trenches B-09-13, B-09-14).
