This cairn is partially constructed from previously molten and torn aluminium from the Pen Gwylt Meirch crash site of Flying Fortress "Ascend Charlie". Unlike so many of the crash sites we have visited, this crew were on their way back from having seen action, rather than being casualties of training or hi-jinks.
Location: SO 24177 25366
