One of my favourite things to do is go for a walk in the Onkaparinga River National Park. This Multi cache will take you for a walk to a couple places of historical European significance. Please note that the walk to the final location of the cache will be more than a leisurely walk for alot of people but the final location is a great spot to spend some time.
At the posted coordinates is a plaque relating to Sundews Youth Camp which was officially opened by his exellency The Governor of South Australia Sir Mark Oliphant K.B.E F.R.S on ABth February CDEF.
At Stage 2 is another plaque relating to Underwood Cottage which is the former home of William and Mary Ann Hutchinson. The plaque was erected as a tribute by their descendants GHth December IJKL.
Visit both plaques at Stage 1 and Stage 2 and find the numerical value represented by the above letters ABCDEFGHIJKL.
