See The Great Cause 1) cache page (Click Here) for the cartridge and the first set of instructions. You must have completed the tasks required for The Great Cause 1) in order to complete the tasks required for this cache.
In order to find this cache you must complete the task of finding the lost treasure of Scotland hidden at Robber's Cave and Robber's Den. Each is worth 20 Kudos points and finding both gains you an extra 10 as a bonus so completing this cache will help you towards your great cause. Unfortunately the locations of the two sites have been long forgotten. Please note that unlike most zones in the cartridge which are always present or only appear if you are within 50kms, the Robber's Cave and Robber's Den zones only become visible when you are within 1km
UPDATE: As the iPhone app has decided to give away the long forgotten locations by ignoring the distance settings in the cartridge here are the locations of Robber's Cave N57°11.277 W002°14.851 and Robber's Den N56°01.459 W005°27.174. These are both real locations. Canmore 19541 and Canmore 39413.
