Fig. 1. A photograph of the third core tube extracted from the area within the magnetic anomaly with soil horizon characteristics and volume magnetic susceptibility. A horizons were often readily identifiable by a poorly consolidated clay matrix with grass roots, high chert content (probably due to deflation) and angular peds. A well-consolidated clay matrix with subangular or more often columnar peds characterized C
Bw-horizons, which generally lacked roots and chert.
