All contacts for FO/K3EL were uploaded to LOTW some time ago, and cards were also sent via the bureau (uploaded to globalqsl.com). Printed cards arrived a few days ago, and so responses to direct requests are now in the mail.
The picture on the card was taken at the Arahurahu Marae, a restored temple on the west coast of Tahiti. There are two replica “tiki”; the originals were once on Raivavae, but now reside at the Musee Gaugin, Papeari, Tahiti (note, at time of writing, the museum is closed for renovations – should be open again later in 2014).
There is a footpath which heads into the forest at the rear of the maintained area at Arahurahu Marae. It roughly follows a river for a couple of km into the mountainous interior of the island. What appears to be ancient agricultural terracing is very visible at the beginning of the trail. The path is fairly clear, although it switches across the stream from time to time, and occasionally fallen trees block the route, requiring a detour. After an hour or so of walking, you come upon another marae, high in the valley.
The walls are overgrown by the forest and covered in moss, but you can still make out the form of the site, locations of different buildings and entrances.
