Excavating Thunder Eggs in Madras, Oregon
Central Oregon is famous among rock lovers for thunder eggs: outwardly plain stone spheres that have fanciful agate cores. At Richardsons Rock Ranch, you can join rock hounds of all ages in the quest for rocks with painterly linings. En route to the rock beds, visit with the ranch's resident peafowl, chickens, and emu. Take a picnic lunch to enjoy in the desert panorama. After the digging is done, ask the staff to saw open your thunder eggs. As the centers are revealed, marvel at the fact that you are the first person to see what was held secret inside for 60 million years.
