This 15-cache geoart was conceived as a way for cachers in Northern Virginia to enjoy a day in Mickie Gordon County Park while gathering enough Unknown caches to satisfy the requirements for three Geocaching souvenirs available on the 2026 Pi Day weekend. Along the way, you can learn a little more about Northern Virginia. In addition, depending on the cache, you will also be exposed to some Pi, Pie, or Pizza (Pie) trivia. Answering the trivia questions will reveal the final coordinates for the cache. You will also have the opportunity to find a Bonus cache for the series.

To determine the cache coordinates for each cache, you will have to answer two questions: one about one of the NoVAGO jurisdictions and the other about either Pi, Pie, or Pizza Pie. The correct city/county answer will provide the decimal minute of the latitude and the Pi/Pie/Pizza answer will provide the decimal minute of the longitude. The degrees and minutes are consistent across the park for both latitude and longitude (N 38 58.nnn W 077 42.www).

Pi Using the Greek letter pi to refer to the ratio of a circle's circumference to its diameter did not occur until 1706 when Welsh mathematician William Jones, although he gave credit to John Machin, who had been on the forefront of calculating digits of pi.
