Ezzo presents a detailed study of the bone chemistry of individuals buried at the 14th century Grasshopper Pueblo site. A wide range of elements were measured from these skeletons as indicators of diet, stress, and nutrition. The different concentrations of these elements were then related to parameters of age, sex, social differences, space, time, environmental change, and possible resource depletion. The major relationships were found to be with sex, space, and time, with significant changes in male and female diets over time, but also with patterned spatial differences in burials suggesting household differences in access to food. This is a data-rich study which provides much information for social and economic reconstructions of prehistoric Pueblo adaptation to their environment.
