Dun Briste, an impressive sea-stack, estimated to be approximately 50 metres in height, stands 80 metres off Downpatrick Head, in the town-land of Knockaun, east of Ballycastle, Co. Mayo. The cliffs in the area, including the stack, were formed in the Lower Carboniferous period, a geological term applied to a time c. 350 million years ago, when the sea temperatures around Ireland were much higher than today. On the adjoining Downpatrick headland, several archaeological monuments may be seen, and these range in type from Bronze-Age ring-barrows, early ecclesiastical sites, the remains of a promontory fort, to a more modern coastguard 'watch-house' of W.W.2 vintage.
along the walk out to the view of the sea-stack from the parking area you will pass by two fenced areas.
the first fenced area is at: n. 54.19.422 w.009 20.816. at this point make an obeservation of how the ocean is changing the ground you are standing on.
the second fenced area is located at: n.54 19.519 w.009 20.809.
look down into the center and observe the action of the waves. proceed to the final location for viewing the the sea-stack at n54.19.606 w.009.20.877.
1a. based on your observations of the two fenced areas, take a guess as to how the sea-stack was formed and send me an email using my profile.
1b. (optional) post a photo of your group clearly showing your gps with the sea-stack behind you.
interesting fact: Some years ago, a helicopter landed several people on the stack; they were the first humans to set foot there for centuries. The party included Dr. Seamus Caulfield and his late father Padraig Caulfield, NT.; Fr. Declan Caulfield, R.I.P.; Noel Dunne, archaeologist; and Prof. Martin Downes, formerly of Castlebar. They camped there overnight and surveyed the surface where they found the remains of a medieval house, cultivation ridges, walls, and a broken quern stone (a stone used for grinding corn). A camera crew recorded the event and a documentary was broadcast on R.T.E. television some time later.
Please begin your e-mail with the name of the earthcache and make sure your log includes the geocaching names and the number of people in your group.
