Map unit “Pioneering Stage” (PURPLE): generally simple stacks of local stones associated with stone piles.
Map unit “Established Farm Stage” (GREEN); Some walls are carefully laid, and stone is much more concentrated.
Map unit “Forest and City Stage” (YELLOW): generally complex variablity, from ancient tumbled walls to estate architecture in yellow areas.
