💎 Hunt geodes and thundereggs

Rockhounding at Richardson's Rock Ranch.

A working rockhound dig site near Madras famous for thundereggs (geode-like rocks with crystal interiors). Rent tools, dig in their stockpiles, and pay by the pound. They cut and polish on-site if you want a finished piece. Pure kid magic for the right kid.

Good to know

  • Bring sturdy shoes and gloves; sun + dust are real.
  • Wash your finds — what looks plain often hides crystals inside when cracked open.
  • Closed Tuesdays; cash works best.
