Big Hole is a large maar (explosion crater) in the Fort Rock basin of Lake County, central Oregon, northeast of Crater Lake, near Oregon Route 31. It is approximately 6000 ft (1820 m) across and 300 feet (91 m) deep. [3] It is close to another smaller, but less-eroded maar crater, Hole-in-the-Ground.
The Big Hole has a surface of 17 hectares (42 acres) and is 463 metres (1,519 ft) wide. It was excavated to a depth of 240 metres (790 ft), but then partially infilled with debris reducing its depth to about 215 metres (705 ft). Since then it has accumulated about 40 metres (130 ft) of water, leaving 175 metres (574 ft) of the hole visible.
The Big Hole – a former diamond mine in Kimberley, dug to 240 m (790 ft) between 1871 and 1914, making it the deepest hand-excavated pit in the world. Now a museum. The Jagersfontein Mine – operating between 1888 and 1971. This was hand-excavated to 201 m (660 ft) by 1911, and the hand-dug pit was sightly larger than the Big Hole.

As material slid into the hole formed, it closed the vent and the process repeated, eventually forming the huge hole. [3] Blocks as large as 26 feet (8 m) in size were flung as far as 2.3 miles (3.7 km) from the crater. [4] To the west of Hole-in-the-Ground is an even bigger maar, 1.1 miles (1,820 m), but older and more eroded, called Big Hole.
This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface ...
