The Triangle / Mesa "Bubble" Anomaly.
allegedanomaly_regionModern Disclosure Nexus
Central focus of the History Channel show: a claimed dome/cone-shaped 'Bubble' (~2000 ft radius) over a triangular area near the Mesa where rockets allegedly fail, drones lose GPS, and UAP appear. LiDAR/GPR reportedly mapped a ~400 ft buried object in the Mesa. The instrumentation effort is documented; the anomaly interpretation is a TV claim with no released raw data.
