Chert, flint and chalcedony are microcrystalline varieties of quartz. Chalcedony is the general term applied to fibrous varieties whereas flint and chert are granular varieties. Flint and chert resemble each other and there is no sharp distinction between them. However, dark, siliceous nodules, usually found in chalk, are called flint; whereas lighter colored bedded deposits are called chert. All three varieties of microcrystalline quartz exist on Flint Ridge.
The Nethers Farm is located at 3680 Flint Ridge Road, north of Hopewell, Ohio.

Nethers Farm is located near the center of the flint deposit. This site has long been open to "modern" rockhounds. For a mere $5.00 collecting fee, you can take home all the rock you can carry for only 50 cents per pound. All one needs to do to collect there is show up on any given day - advanced notice or a reservation is not necessary. The side porch is left open and the directions on how and where to collect and pay your fees are left hanging next to the inside door above a large scale.
When you're done collecting, you must visit the side porch to weigh your rocks, calculate your total fee ($5 plus 50-cents per pound of rock). The money is to be put in a furnished envelope and slipped under the inside door. If nobody is around to collect your fee, this works on the honor system, so be please be honorable should you decide to visit the Nethers Farm.
The two-track dirt road leading to the collecting area is directly across the street from the farm.
PLEASE NOTE: this post does not imply permission to collect flint at the Nethers Farm. Please inquire before collecting! This is rare that a collecting site has remained open to the public all these years.
