It depends greatly on whether the materials used were logs or poles.  In general, upright poles were used as a frame for a jacal structure (cf. wattle and daub).  The poles were used as a frame on which to place a relatively thick coat of adobe mud.  it was a fast way to erect a livable structure.  These buildings offered almost all o the benefits of an adobe building without the hassle of making the bricks.  I photo would help a lot with this.
