| Caption | Chamise root in a mesquite sand dune. Chamise root turned abruptly and proceeded horizontal to the surface just above zone of compaction. Mesquite roots penetrated zone of compaction and 4 feet of caliche lying immediately below. Mesquite roots were followed to a depth of 14 feet and 2 inches. Large chamise roots are profusely branched by fine fibrous roots from the surface downward. Mesquite roots offer but little competition to chamise roots in first foot below the surface.
