Inscription
Oil was first struck here in 1890, and in 1891 and 1892 the field yielded the highest levels of oil in the world. Second only in Pa. history to the Bradford Oil Field in both size and production, it was instrumental in achieving the state's highest ever annual oil output in 1891, 31,424,000 barrels.
The wells achieving Pennsylvania's highest daily oil production rates, Mevey No. 1 and Mathews No. 1, were located within three miles of here.
