Silverpit Crater - The concept of a meteoric impact crater in the North Sea was first proposed in 2002 by Simon Stewart (BP) and Phillip Allen (Production Geoscience). The discovery of the unusual concentric ring pattern was found during routine petroleum exploration of reserves beneath the floor of the North Sea. Click pin to read the full article.

Young earth v. old earth: If this had happened sometime within the last 6,000 years, I kind of think it would have been noticed. :)  "The multiple-ringed Vredefort Crater - The asteroid that hit Vredefort is estimated to have been one of the largest ever to strike Earth (at least since the Hadean Eon some four billion years ago), thought to have been approximately 5–10 km (3.1–6.2 mi) in diameter. The bolide that created the Sudbury Basin could have been even larger."

Monturaqui Crater - The Monturaqui Crater is located south of the Salar de Atacama in Chile. The present dimensions of the crater are approximately 460 meter (1,509 feet) in diameter by 34 meter (100 feet) deep. The impact probably occurred about a million years ago. Because of the extreme arid conditions of the area the crater is still clearly visible.
