FIELD DESCRIPTION

A spiral formation documented in 1991. Diameter approximately 97 meters.

AERIAL PHOTOGRAPH

What Are Node Anomalies?

In genuine crop formations, the plant stems are bent — not broken — at the nodes (growth joints). This bending is accompanied by elongated nodes and sometimes expulsion cavities — small holes blown through the node wall from the inside, consistent with a rapid, intense heat source.

Confirmed

Node elongation and/or expulsion cavities confirmed by field investigation. Inconsistent with mechanical flattening.

Not Present

No node anomalies detected. Formation may be man-made or insufficient investigation was conducted.

Unknown

Node status not recorded or formation was not physically investigated by researchers.

Research by BLT Research Team (W.C. Levengood, Nancy Talbott) documented node elongation in 300+ formations across 30+ countries. The phenomenon requires a brief, intense electromagnetic or microwave energy source — incompatible with boards and rope.
