Earth Treasures Books in Order

Earth Treasures is Allan W Eckert’s four‑volume field guide set for people who like to get their boots dusty in search of rocks, minerals, and fossils. Instead of focusing on abstract geology, the series is built around actual places you can visit by car and explore on foot.

Each volume covers a different quadrant of the United States. Together they describe thousands of sites across the country, from road cuts and streambeds to old quarries and abandoned mines. Within each region, entries are organized by state and county so that readers can match what is on the page to what they see on road signs.

At the heart of the books are the maps and directions. Every volume includes hundreds of to‑scale county maps marked with numbered collecting locations. The text then walks you into each site, noting landmarks, turnoffs, and terrain so you have a practical sense of where to park, where to walk, and what you are likely to find there.

For each locality, Eckert notes the types of material that have been collected in the past: common gemstones, interesting minerals, fossil beds, or just good general rock‑hounding ground. He also offers basic guidance on how and where to search once you arrive, making the series approachable for beginners as well as useful for more experienced collectors planning new trips.

Because the books focus on drive‑to sites rather than remote wilderness, they are especially handy for families and hobbyists who want to combine collecting with everyday travel. The tone stays practical and down‑to‑earth, with just enough background on geology and fossil formation to help readers understand what they are seeing without turning the series into a textbook.

Readers who enjoy planning outings, marking maps, and bringing home a few well‑earned specimens will find in Earth Treasures a detailed, region‑by‑region companion for exploring the ground beneath their feet.
