The newest campaign from Geocaching, called Wonders of the World , begins August 12 and runs through, at the least, December 31, 2020. In this campaign, you can earn up to three souvenirs by finding geocaches and earning stamps for your Wonders of the World passport . The three souvenirs that can be earned are: Modern Wonders of the World Ancient Wonders of the World World Explorer Similar to Mystery at the Museum , each cache will have a digital passport stamp. All seven of the Modern Wonders of the World passport stamps need to be collected in order to unlock the Ancient Wonders of the World. After all seven of the Ancient Wonders of the World passport stamps have been found, and your passport is full, you will have earned the title "World Explorer." This campaign will definitely help me with the Memory Lane campaign, which I have not completed, yet. I'll enjoy getting "two-for-one" credit on these caches.
