Mystery AtlasWilkes Land Gravity Anomaly
A roughly 480-kilometre satellite-measured mass concentration beneath the East Antarctic ice sheet, first proposed as an impact crater in 1962 and identified via NASA GRACE gravity data in 2006; its origin, an ancient asteroid impact or a mantle plume, remains an open scientific question.

Theories & Explanations
Wilkes Land Gravity Anomaly is frequently confused with Antarctic Subglacial "Lost City" Claims — Viral posts have cited the real, unresolved GRACE gravity anomaly as 'evidence' for hidden structures or a cover-up, conflating a genuine open geophysical debate (impact crater versus mantle plume) with baseless claims of artificial construction.
Places
Wilkes Land Gravity Anomaly is frequently compared to Lake Vostok — Both are headline examples of large-scale features identified beneath the East Antarctic Ice Sheet through remote geophysical sensing rather than direct observation.
