Above-ground construction is of jacal or crude masonry. This type of house is called a "jacal". A heavier line of poles extends the length of the jacal. Jacal construction is similar to wattle and daub. At the beginning of the period pueblos were made with jacal construction. The building materials for the walls could include stacked logs, jacal or poles and brush. Jacal walls were also found to be used at this site. Jacal walls were made from a screen of upright wooden poles plastered together with mud. Luna's jacal was placed on the National Register of Historic Places in November 8, 1974.
