Thunder, Tremor, and Stones: Guernsey County, 1860

Before the stones fell, people heard a thunderclap and felt an extraordinary shock like an earthquake.

The fall was observed across an area about 10 miles long and 3 miles wide.

More than 30 stones were recovered; Gibb reports weights ranging from half a pound to 103 pounds.

The irregular stones had smooth, black, glassy-looking surfaces; their ashy interiors held fine shining particles thought to be nickel.
