Richard.F: The hollow concrete block that had been placed at location 4FRW4FRW+XX (which was an arbitrary location -- apart from the repeating numbers and letters of the name -- in seasonally flooded wild grassland) has been removed by persons unknown. As there is no reasonable way of placing a regular replacement cache at this precise location in anything other than a sizeable outer covering, and a micro container in knee-high grass would be worse than the proverbial needle-in-a-haystack, this cache is archived.
