Check out Dale Weisman's feature on rock hunting in the February issue. A lifelong rockhound, Dale logged hundreds of miles researching this piece, scouring rock-hunting ranches, rivers, roadcuts, and rock shops across the state. He offers the following suggestions for further reading: Gem Trails of Texas, by Brad Cross; The Rockhound's Guide to Texas, by Melinda Crow; and Roadside Geology of Texas, by Darwin Spearing.
I concur with Dale on the wonders of Woodward Ranch. Two tips if you go: Ask Trey Woodward to show you the gemstone-studded mantel in his home, and pick up a hand lens (around $16) in his rock shop for spectacular crystalline close-ups.
Let us know about your cool rock and fossil finds. Happy hunting!
