The Crestone Crater in Colorado is a fascinating site that sparks curiosity among scientists and adventurers alike. It appears to be a meteor impact, but the evidence is still sketchy. Located on the north side of the Great Sand Dunes National Park and Preserve in the San Luis Valley, this elliptical bowl measures about 355 feet by 246 feet, with an average depth of 23 feet.
Historical accounts tell of a fireball falling from the sky in 1892, hinting at a potential meteor event. However, the crater itself wasn’t discovered until 1934 by a local resident. In 1941, geologist Dr. H. H. Nininger was the first to study the crater and believed it was formed by a meteorite. Yet, a later investigation in 1963 by scientists Ursula and T. C. Marvin found no concrete evidence to support that idea. Their study revealed only trace amounts of nickel-iron spherules and concluded that wind likely shaped the crater instead.
Recent evaluations from the National Park Service still leave the door open for the meteorite theory, suggesting that any physical evidence might be buried beneath the surface. A noteworthy study by students from the Colorado School of Mines challenges the wind theory by highlighting distinct geological features beneath the crater that could point to an impact scenario.
If the Crater really is an impact site, it’s remarkable due to its tiny size and preservation in the sands. The unique characteristics observed could be considered geological anomalies. Current investigations are using ground-penetrating radar and magnetometers to delve deeper.
Some theories even propose that the crater might be a result of a ‘sand boil,’ formed by water pressure pushing up sandy deposits, complicating the discussion further.
The San Luis Valley, where the Crestone Crater sits, is also known for various strange occurrences, including UFO sightings. This adds a layer of intrigue to the crater, with some speculating it could even be the mark of an alien craft.
As research continues, the mystery of the Crestone Crater is far from solved, inviting ongoing exploration and discussion. For those interested, the crater can be accessed via the Liberty Gate Trailhead at the Great Sand Dunes National Park and Preserve.
