Oil boom of 1906
|This section does not cite any references or sources. (April 2012)|
In 1906, John Shire and several men tossed an empty whiskey bottle in the air and drilled where it landed. Fourteen feet was drilled until a gusher of petroleum was struck. The villages of Stoy and Oblong became tent cities. From 1908 to 1910, Crawford County was credited as being the greatest petroleum producing area in the world.
Oil is still produced throughout Crawford County to this day.
