Banda Research Project team members Courtney Amos (left), Leith Smith (center) and Emmanuel Duku (right) document the stratigraphy and soil characteristics of the west wall of unit 68E 4N at Mound 129, Kuulo Kataa. Duku measures the boundaries of stratigraphic layers using a metal tape measure and a level string anchored midway down the profile wall. Amos uses graph paper to create a profile map, marking the locations of points measured by Duku. Smith uses a Munsell Soil Color Chart book to record the color of soils from top to bottom along the profile wall. Kuulo Kataa, 2000.
