AI-Generated Summary
A 1946 Swedish military report investigates a circular hole in the ground near Garphyttan suspected of being an impact site. Investigators determined the hole was a natural geological collapse caused by a spring, likely exacerbated by an animal stepping on the surface.
This report, dated August 5, 1946, details an investigation conducted by Eric Malmberg and an officer named Sillén from the Örebro military staff (fo-stab). The investigation was prompted by reports from the public near Garphyttan, Sweden, regarding a small, circular hole in the ground. Because local residents had observed a light phenomenon in the area a few days prior, there was speculation that the hole might be the result of an impact event. Upon inspection, the investigators found a circular hole measuring 230 mm in diameter, which led to a larger underground cavity 2.2 meters in diameter and 1.5 meters deep. The investigators examined the site for evidence of an impact, such as signs of gas-related pressure or structural damage, but found none. The turf removed from the hole showed no impact markings. Further excavation revealed that the cavity was formed naturally; a spring flowing through moist soil layers had undermined the ground, creating an underground space. The investigators concluded that the circular hole was created when a large animal, likely a horse, stepped through the weakened roof of this naturally occurring cavity.

Official Assessment
The hole was caused by a large animal, likely a horse, falling through the roof of an underground cavity formed by natural erosion.
The site was investigated following reports of a potential impact site, possibly linked to a light phenomenon seen days earlier. Excavation revealed the hole was not caused by an impact, but by the collapse of a cavity created by a spring flowing through moist soil layers, which had undermined the ground.
