A good impression of the major areas of terracing across the island
is offered by the Hellenic Military Geographical Service's 1:5,000
maps, but these nonetheless heavily underpresent the overall amount
of land that has been invested with such works in the past. KIP geoarchaeologists
have sought to create a more detailed map of such structures within
each of the geoarchaeoligcal survey zones.
There are two reasons for this level of attention: firstly, depending
on the method of their construction, terraces can either reveal archaeological
sites or, more commonly, impede their detection. Indeed, previous
fieldwork has clearly demonstrated several examples of primary context
settlement remains completely buried by terracing. Secondly, numerous
parts of the landscape have been terraced more than once, a poly-cyclic
process far from being restricted to Kythera, and with significant
implications for landscape history and the interpretation of survey
data from slope environments in the Mediterranean. Oddly, there are
very few accounts of the manner in which terraces fail, or of the
time necessary for terraced slopes to revert once they are abandoned.

Geoarchaeological research therefore seeks to shed new light on these
two issues, not only through its own fieldwork, but also through correlations
with the survey data, and historical insights from archival research.
All three geoarchaeological areas were significantly more terraced
than was initially appreciated. The majority of the water gathering
slopes in the mapped area appear to have been cross-channel terraced
(to harvest water run-off and small patches of Quaternary alluvium).
Somewhat more surprising is the extensive amount of contour terracing,
particularly on freshwater Neogene conglomerate, Eocene flysch formations
or near freshwater spring vents.
