Flint Ridge |
|
Flint Ridge is located in East Central Ohio, east of Newark and west of Zanesville. It’s located in a line of rugged hills that are actually an irregular plateau, running east to west. Elevation averages 1200' above sea level, decreasing gradually toward the eastern. The area of the Ridge is approximately 6 sq. miles. |

This flint (actually classed as chert) is known geologically as “Vanport” of the Pennsylvanian age of the Allegany Region. The flint deposits are anywhere from 1-12’ in thickness but average 4-6' in thickness. It rests above fossilferrous shale or limestone. Flint from the Ridge is predominately gray in color, but added impurities make up the color in the stone. Every color of the rainbow is found at Flint Ridge, in reds, blues, white, yellow, orange, brown, black, and rarely green (only from heat treating) or purple. |
