Agates Field Guide
By Dan R. Lynch and Bob Lynch
Adventure Publications, $12.95
This isn’t the first book published by the father-and-son duo from Two Harbors. Agate pickers of all experience levels should find this 161-page field guide appealing and useful, with color pages and clear descriptions of the many types of agates, which are perhaps Lake Superior’s most appreciated gem.—Javier Serna
