10 Most Incredible Impact Craters

10 Most Incredible Impact Craters

NATURE
An impact crater, also known as meteorite crater is a crater created by a collision of a meteorite with the Earth surface. The following is a list of 10 impressive impact craters that can be seen and recognized by the naked eye. Therefore, the list contains small craters, rather than huge crates which are tens or hundreds of kilometers in diameter
1. Meteor Crater (Barringer crater), Arizona, United States – The Barringer crater is one of the best preserved impact craters in the world. The impact occurred about 50,000 years ago by an iron meteorite – very recent with regards to meteorite impacts. It has a diameter of 1,200 meters (3,900 ft) and a depth of 170 m deep (570 ft). The crater is named after Daniel Barringer who was first to suggest that it was produced by meteorite impact. The Meteor crater is a U.S. National Natural Landmark and resides on a privately owned property

2. Pingualuit Crater, Quebec, Canada – The Pingualuit crater, also known as Chubb Crater or New Quebec Crater is located in the Ungava Peninsula. It is 3.44 km (2.14 mi) in diameter, and has a depth of 400 m (1,300 ft). The impact occurred around 1.4 million years ago – older than Meteor Crater, but still young for an impact crater. The crater is filled with a lake called Pingualuk Lake

3. Amguid Crater, Algeria – The Amguid crater is an impact crater with a diameter of about 500 – 530 meters (1,640 – 1,740 ft) and a depth of only 65 meters (213 ft). The crater was first descovered in 1948 and it is estimated that the impact occurred less than 100,000 years ago

4. Lonar Crater, Maharashtra, India – The Lonar Crater age is somewhat controversial: the age is usually estimated to be around 52,000 years, but recent studies indicate that the impact might have occurred as much as 570,000 years ago (give or take 47,000). The meteor crater rim is about 1.8 km (5,900 ft) in diameter and is filled by the Lonar Lake which has a diameter of 1.2 km (3,900 ft)

5. Wolfe Creek Crater, Western Australia, Australia – Located within Wolfe Creek Meteorite Crater National Park, this well preserved meteorite crater was first found in 1947. It is about 875 meters (2,870 ft) in diameter and has a depth of about is 60 meters (196 ft). The age estimation is less than 300,000 years

6. Tenoumer crater, Mauritania – Located in the western Sahara Desert, this impact crater is 1.9 km in diameter, with edges that rise up to 110 meters above the crater’s base. It is one of the youngest of the craters in this list with an estimated age of somewhere between 10,000 – 30,000 years

7. Tswaing Crater, South Africa – This crater is also filled with a lake. The crater has a diameter of 1.13 km and a depth of 100 meters. The impact occurred some 220,000 years ago

8. Kaali Craters, Saaremaa island, Estonia – Kaali is a group of 9 impact craters formed 4,000 -7,600 years ago, as a meteorite broke into pieces at an altitude 5 – 10 km and fell to the surface in fragments. The falling fragments created 9 rather small craters all within a radius of 1 km (0.6 mile). The largest crater has a diameter of 110 meters (360 ft) and a depth of 22 meters (72 ft), while the rest are only 12-40 meters in diameter and just 1-4 meters in depth

9. Aouelloul Crater, Mauritania – Another exposed impact crater in Mauritania, 390 meters wide with an age estimation of over 3 million years

10. Roter Kamm Crater, Namibia – Located in the Namib Desert, the crater is 2.5 km (1.5 miles) in diameter and is 130 meters (430 ft) deep, although most of it (at least 100 meters / 330 ft) is filled with sand. The age estimation is 4-5 million years
