The Victoria Island structure is a 5.5 km (3 mi) bowl-shaped structure buried in the shale sediments of the Sacramento-San Joaquin River Delta, 12 miles (19 km) west of Stockton, California. The circular structure is part of a former sea bed, and lies 1,490–1,600 meters (4,890–5,250 ft) below sea level.[2]
Discovered during oil exploration and reported at the Lunar and Planetary Science Conference in Houston, Texas, in March 2007, it is thought to be a buried impact crater formed between 37 and 49 million years ago.[3][4]
Victoria Island, which the structure is named for, is in the San Joaquin River Delta at approximately [ ⚑ ] 37°53′24″N 121°32′06″W / 37.890°N 121.535°W.[5] The current publications do not list a more precise location for the impact structure than the island.
