Geological Chronicle

St. George crater sits on the west slope of Mons Hadley Delta, roughly 4 kilometers southwest of the Apollo 15 landing point in the Hadley–Apennine region. Bridge crater lies to its northwest and Elbow crater to its northeast.

During EVA 1 of Apollo 15 in 1971, David Scott and James Irwin drove their rover onto what was suspected to be the crater's ejecta blanket, collecting samples at Geology Station 2 to the northeast of the crater.

St. George is of Upper (Late) Imbrian age. The International Astronomical Union formally adopted the name in 1973.

Chronology & Exploration

1. Late Imbrian Crater formation

   St. George formed during the Upper (Late) Imbrian period, one of the Moon's major impact epochs.

2. 1971 Apollo 15 EVA 1

   Scott and Irwin drove onto the suspected ejecta blanket of St. George and collected samples at Geology Station 2 during the first moonwalk of the mission.

3. 1973 IAU name adoption

   The International Astronomical Union formally adopted the name St. George for the crater.
