County Chert Maps

This part of the website is temporarily unavailable as we are switching to a new web-based format that is more user-firendly and includes much more information such as pictures of chert samples, higher resoultion maps, and information on knapping quality.

We hope to have this web mapping interface available by April 1, 2017. In the meantime, please contact Chad A. Goings at cagoings@rollinghillsconsulting.com with any questions or products on chert in Iowa.
