Traditional cache
From GeoWiki
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. This waypoint and location were listed on one of the [geocaching sites]. These hides 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. It is probably a straightforward walk to "Ground Zero" and search for the cache.
Caches with multiple waypoints, puzzles or offsets are not traditional.
