Monthelie, if you look at the attached link, you will see a big pink anomaly located beneath Zona Central.This image was derived from the results of the Stage 1 Titan 24 Geophysical Survey.It is 1,450m long x 400m x 300 - 500m thick.We all enjoy seeing the math that provides estimates on the gold this anomaly may contain.If you do a keyword search on "ovoid" you will see plenty of posts from the St. Elias hub on this topic.
