Linear Anomaly 2 is striking. It is a larger 150 nT amplitude anomaly aligned to
the west-southwest and extending for 100 m, and demonstrates the same noteworthy
uniformity and cohesion. Specifically, Linear Anomaly 2 consists of a broad negative
anomaly, bounded along its lateral sides by lower amplitude positive anomalies. The
anomaly begins approximately 30 m west of the Olmec throne location in Field 8. The
medial axis of this anomaly is aligned with Structures 77a and 77b and, if it were
extended eastward, it would intersect with the throne (Figure 4.24). Beyond the clearly
delineated 100 m long anomaly, the anomaly continues but weakens, causing a loss of the
positive values, coherence and amplitude. This decrease may be due to the combined
effects of the Throne Complex Platform and Structures 77a and 77b covering and,
