Depuyer, MT: Mutilated calf found in hydrophobic soil circle
In October 2007, a rancher discovered a mutilated calf lying inside a 33-foot diameter circle of hydrophobic soil in Depuyer, Montana. The ground within the formation exhibited unusual water-repellent properties and a glossy surface, while surrounding areas were muddy from precipitation. Laboratory analysis later identified trace amounts of potassium nitrate in the soil, though the source of this chemical remained unexplained.
Background
In October 2007, a cattle rancher in Depuyer, Montana made a disturbing discovery on his property. After precipitation one evening, he found a mutilated calf positioned on the southern inner rim of a perfect 33-foot diameter circle of dirt. While the surrounding ground had become muddy and difficult to traverse due to rain and snow, the soil within the circle remained surprisingly firm and exhibited highly unusual characteristics.
The dirt inside the formation displayed hydrophobic properties, causing raindrops to bead up and roll off its glossy surface rather than being absorbed. Additionally, the soil appeared noticeably lighter in color compared to the surrounding area, and vegetation stubble within the circle was flattened. These physical anomalies suggested the possibility of anomalous activity or exposure to unknown substances.
Subsequent laboratory analysis of soil samples revealed the presence of potassium nitrate in concentrations of less than 0.5 weight percent at various locations within the circle, though notably absent from a control sample taken ten feet south of the calf. While this compound is commonly used in fertilizers, the specific formulation used by the farmer contained higher concentrations of phosphorus, which was not detected in the samples. This discrepancy, combined with the chemical's association with pyrotechnics and rocket propellants, has raised questions about the origin of the substance and the nature of the event itself.
