A simple stone marker in Papago Park, on the south-western edge of Scottsdale, identifies the site of the largest prisoner-of-war escape on American soil during the Second World War. The camp itself is long gone — the buildings were dismantled in the 1950s — but the marker, the surrounding desert, and the famous "buttes" of the park give a sense of what the prisoners faced.
The tunnel exit was rediscovered in the 1980s. Combine with a visit to the Desert Botanical Garden a few minutes' walk away.
