South Cadbury Environs Project The project began with very ad
hoc gridded fieldwalking, targeting areas thought promising.
This eventually developed into corridor walking, a system using
1m wide contiguous 20m long strips. Fieldwalking was abandoned
in favour of shovel-pitting although some restricted surface
collection continued on some plateau areas. Corridor
fieldwalking by University of Birmingham postgraduate students,
1998. After its first successful use during the Sigwells pilot
study, shovel pitting (sieving a fixed amount of soil at regular
intervals) was employed to reduce variables associated with
surface conditions. Ultimately however, like fieldwalking, it
proved ineffective on middle to lower valley sides and bottoms
and the open plain due to soil movement.
