Listing of feature-level functional observation criteria discussed in the text and applied to the 19 individual Norse r uins considered in present study, as well as three comparable features at L’Anse aux Meadows, Newfoundland (LAM Hall A, D, and F). Observation criteria include: feature dimensions and wall width(s) (showing variation and average); wall and building materials identified using th e classification scheme in Table 1; number of identified rooms; orientation of buildings (if applicable); wind exposure; and building ground.
