The GeoTriad refers to a specific set of three geocache sites within the Pacific Northwest. Two are located in and around Seattle, WA, while one is located just outside of Portland, OR.
Description[]
Attempting to complete the GeoTriad is a popular goal of geocachers traveling to the Seattle/Portland area. The three geocaches would be considered part of Geocaching history by many. They include:
- Project A.P.E. - Mission 9: Tunnel of Light
- Geocaching headquarters
- The Original Geocache
There is a Challenge Cache dedicated to completing all three GeoTriad caches[1]
