The Petriverse has been designated a “Geotour de Force” by Golden State GeoTours. The rare honor recognizes particularly powerful lithic locations in California, where geophysical energies and aesthetic splendor combine to attract rockhounds and stone lovers. Canonical sites include Skull Rock in Joshua Tree, Devils Postpile, and Half Dome in Yosemite. “We felt that The Petriverse displays a unique geophilic fervor, in its commitment to creating strangely attractive stone displays and attractively strange rock messages,” GSGT President Jon Mewer stated. A dewy-eyed Pierre Jardin called it “a truly unexpected honor,” acknowledging that his humble suburban rock garden cannot compare with large-scale formations on the club’s list. “While those places are authentic natural wonders, the Petriverse is, naturally, about making you wonder,” Jardin concluded enigmatically.
