Box 6331 Dunedin New Zealand 2007 Denniston Archæological Survey 1 The Eighth Wonder of the World It is an often-told story that, when in March 1889 a hurricane hit Apia in Samoa, it was the high quality Denniston coal carried by H.M.S. Calliope that enabled her to raise steam and avoid disaster when other warships in the harbour were wrecked. Between 1880 and 1967 the Denniston Incline worked to bring this first class coal down from the Denniston Plateau to the wharves at Westport. The incline itself was regarded by locals as ‘the eighth wonder of the world,” descending at grades of almost 1 in 1.25 in places, bringing 105 tons of coal an hour down 1,700 feet from the plateau. It stands as one of New Zealand’s foremost Victorian engineering structures, built at the height of the railway and steam age. The Denniston Incline is now managed by the Department of Conservation as an historic site, and conservation and restoration work is currently underway to improve the interpretation of this site to visitors. In late 2006 an archæological survey was carried out in order to record details of the incline and associated sites, and help guide future conservation work. Denniston Archæological Survey 2 Acknowledgements I would like to thank a number of individuals and organisations for their assistance during this survey. The West Coast Conservancy of the Department of Conservation funded the survey and provided logistical assistance. In particular Jackie Breen of DoC co-ordinated the work and assisted in the field during a very wet ten days, many of which she spent bashing though gorse. I would particularly like to thank Carmen Sarjeant of the University of Otago, who also assisted during the survey, and spent numerous hours standing at a water-logged plane table. Gary James of the Friends of the Hill provided warm hospitality on a particularly wet day, acted as a guide around the historic sites in the township, and provided clarification over a number of historical details. Kevin Jones of the Department of Conservation in Wellington kindly supplied copies of his recent detailed low-altitude aerial photographs of the mining sites on the Denniston Plateau. My father, David Petchey, provided engineering advice, particularly regarding the oft- misquoted fact that the incline used 4 inch diameter wire rope (actually 4 inch circumference rope). The New Zealand Railway and Locomotive Society gave permission to reproduce images from Bob Meyer’s excellent publication Coaling from the Clouds. I would also like to acknowledge the work of Sonia and Terry Sumner, whose 1983 survey of historic coalmining remains was used extensively in the preparation of this report. Their work was so comprehensive that in places all that was really required was the preparation of accurate maps and plans and an update on the condition of sites.
