Although this site has been worked by rockhounds for many years, quality thundereggs can still be found by determined rockhounds. Digging through the tough rhyolite matrix can be difficult so be sure to bring hand tools adequate for breaking rock. Look for chips and pieces of agate where other rockhounds have been digging for potential leads.
