Colorado Gem Trails and Mineral Guide — 1972 ·

By Richard M. Pearl

This famous book takes you on an extensive gem and mineral collecting tour of Colorado, revealing the interesting places where Nature has stored her treasures.

Detailed directions are given for reaching the noted as well as the little-known localities in all sections of this great mineral-producing state. Included are numerous mileage logs never before published, and many sketch maps made especially for this book. A unique system arranges the localities along segments of the main highways.

Latest information is given on local travel and collecting conditions and land ownership, so much desired by collectors who want to make the best use of their time. Gem and mineral societies that welcome visitors—museums that display outstanding collections—are all described. Official maps and references to the literature are listed.
