To honor 20 years of geocaching, this series has been placed on the Redbank Valley Trail to highlight the 10 oldest still active geocaches in the state of Pennsylvania. There is only one cache left in Pennsylvania from the year 2000. The rest are from 2001. (Note that in the very beginning caches were not always numbered sequentially by the date they were placed.) Trail is open dawn to dusk.
4th oldest - GC2EA, Chinese Cache, placed 2/18/01, Schulkill County
