Fact Check: Largest Impact Crater in Australia

What We Know

Australia is home to several notable impact craters, but the claim regarding the "largest impact crater" can be misleading. The most recognized impact crater in Australia is the Wolfe Creek Crater, which measures approximately 875 meters in diameter and is located in Western Australia. It is often cited as one of the best-preserved meteorite impact craters on Earth.

However, recent geological studies have suggested the existence of a much larger impact structure buried beneath the surface in southeastern Australia. This structure, which could measure around 520 kilometers in diameter, has been identified as potentially the largest impact crater on Earth, surpassing the previously recognized Vredefort crater in South Africa, which is about 300 kilometers wide (Australian Geographic, Live Science). This buried structure is believed to have formed over 500 million years ago and has not yet been fully confirmed as an impact site due to the challenges of accessing and studying it.

Analysis

The claim that Australia has the "largest impact crater" is partially true, depending on the criteria used. If we consider only confirmed craters, Wolfe Creek is the largest recognized impact crater in Australia. However, the discovery of the potential 520-kilometer-wide structure raises questions about the definition of "largest."

The sources discussing the buried crater, such as BBC News and Forbes, provide credible geological evidence suggesting its existence, but it remains unconfirmed in the same way that Wolfe Creek is. The buried crater's identification relies on geophysical evidence rather than direct observation, which introduces a level of uncertainty. The Earth Impact Database, a primary source for impact structures, lists confirmed craters but does not yet include this newly suggested structure (Wikipedia).

The reliability of the sources discussing the buried crater is generally high, as they are based on scientific research and geological surveys. However, the interpretation of this evidence can vary among experts, leading to differing conclusions about the crater's status.

Conclusion

The claim that Australia has the "largest impact crater" is Partially True. While Wolfe Creek Crater is the largest confirmed impact crater in Australia, the potential discovery of a much larger buried impact structure suggests that Australia may indeed have the largest impact crater on Earth, though this remains unverified. The distinction between confirmed and unconfirmed craters is crucial in evaluating the claim's accuracy.

Fact Check: Built on ancient Native American mounds near the meeting point of where the Ohio and Mississippi Rivers clash, the town sits at a natural crossroads. During the Civil War, that geography turned it into a vital Union stronghold. Mound City became home to one of the largest military hospitals in the West and served as a major naval station. Soldiers from both sides passed through some to recover, many not. It may be quiet now, but this place once pulsed with the urgency of life and death and sat at the crossroad of a nation at war with itself. That history lingers most clearly at the Mound City National Cemetery, just beyond the edge of town. I wasn’t expecting to find it, and I certainly wasn’t expecting the names etched into some of the stones. Two men in particular stood out, John Basil Turchin and Alexander Bielaski. Both born in the Russian Empire. Both connected to Abraham Lincoln. Both now buried here, far from where they began. John Basil Turchin (born Ivan Turchaninov) had once been a colonel in the Russian Imperial Army. He fought in the Crimean War before immigrating to the United States in 1856. When the Civil War broke out, he offered his experience to the Union cause with fierce conviction. His military background and abolitionist ideals caught Lincoln’s attention, and he was appointed a brigadier general, becoming the only Russian born general to serve in the Union Army. He died in 1901 and was laid to rest here, among the soldiers he once led, and some that he fought against.
