While I’ve been geocaching for years both all over the US and in other countries, I have just recently discovered earchcaching. An earthcache is a natural geologic formation, so nothing is hidden at these sites. Instead, to get credit for finding one of these, you must answer some questions about it. I have now reached the Bronze level in finding earthcaches, which means I have found a total of three, but found in at least two states. A mere neophyte!
