The TBI Field School is situated in a broad and arid steppe, inhabited by Turkana pastoralists thought to have arrived in the last 300-400 years. The Turkana raise cattle, sheep, goats and camels, and are traditionally mobile, following rain and pasture with their herds. To differentiate the valuable herds or flocks of different families, the Turkana will often use branding symbols inherited from their fathers, or clans. Curiously, some of the symbols used by the Turkana for branding also appear on ancient structures built long before the Turkana arrived. To investigate this mystery, Veronica Waweru and TBI students visited a local camel herder of the Nachichechok clan, to ask about the meaning of his branding symbols.
