Traditional cache
From GeoWiki
Traditional caches:
The reason for calling them traditional is; the first few original locations were created and placed in this fashion. A container, of regular or average size, was hidden in the location,and the GPS co-rdinates (Waypoint) taken. then this waypoint and location were listed on one of the geocahcing sites. these hide did not involve any puzzle solving or multiple locations.
So a "traditional" cache is one that has a single waypoint and is generally of a regular size. One that is probably a straightforward walk to Ground zero and search for the cache.
