Abstract: A survey of the caves of Bishopston Valley, Gower, published previously in Cave and Karst Science (2010: Vol.37, No.2), identified cave sites with the potential to contain archaeological material within their sedimentary deposits, and assessed the conservation status of these sites. Two caves – Ogof Ci Coch and Valley Side Cave 1 – showed clear signs of recent anthropogenic and/or biogenic disturbance of their fill. Archaeological test excavation at both sites was undertaken in summer 2011, and the results are reported here. Ogof Ci Coch is demonstrated to be an archaeological cave containing Mesolithic and later prehistoric artefacts. However, archaeological material was only found within spoil deposits from a caving dig, now overlying intact but archaeologically sterile deposits near to the mouth of the cave. Archaeological interpretation of this material is therefore limited in scope. Valley Side Cave 1 was found to contain only disturbed deposits which are clearly the result of recent unauthorised excavation at the site. These findings have implications for the conservation and management of cave sites in Bishopston Valley.Received: 02 April 2012; Accepted: 01 August 2012.© British Cave Research Association 2013ISSN 1356-191X

At the Buchan karst in southeastern Australia, Early Devonian carbonates contain >700 caves and karst-related features. The Potholes, in the northern part of the karst, is a densely cavernous area with >100 caves and 60 dolines over only ~0.8 km2. The caves here are predominantly vertical and the roofs commonly show smooth upward steps, indicative of having formed by rising groundwater. Because of sea level fluctuations during the Early Devonian, the limestone at The Potholes forms a tongue that lenses out to the south and is overlain and underlain by relatively insoluble marl. Mapping of fluvial sands and gravels and valley-filling basalt shows that in the Paleogene, the limestone lay beneath a broad, southwards-flowing river valley. Cave development occurred along phreatic loops within the limestone underneath the riverbed, and the upwards limbs of these phreatic loops were focussed into a small area where the limestone lensed out. The concentrated upwards groundwater flow, which connected to springs in the riverbed, resulted in intense cave development within a restricted area, where the groundwater exploited many different pathways within the limestone. The Potholes caves developed entirely beneath the riverbed, and are notable in that numerous caves fed multiple resurgences rather the more common situation world-wide of a single passage connecting to a resurgence. Both these characteristics reflect the unique geological configuration of the site, and show how karst development is determined by the particular arrangement of soluble limestone beds. Dissolution of The Potholes caves could have begun in the mid-Cretaceous, when uplift increased the gradient of the ancestral river flowing over the limestone, driving groundwater flow through phreatic loops beneath the river, and terminated when the caves were drained following a second uplift in the mid-Pliocene. This demonstrates the antiquity of cave formation in this part of Australia.

THIS ARTICLE IS A SUMMARY site report of excavations at Musang Cave, a limestone cave located in the municipality of Penablanca, in northern Luzon, Philippines (Fig. 1). The cave is in the western foothills of the Sierra Madre. There are many archaeological sites in this region. From November 1976 to Feb ruary 1977 researchers from the National Museum of the Philippines conducted an archaeological survey of approximately 35 km2 in the area surrounding Musang Cave. In all, 71 caves and 7 rock shelters were located, 43 of which have archaeologi cal remains. These are primarily habitation sites. In addition, 21 open sites, lithic workshops, and habitation sites were found (Ronquillo and Santiago 1977). Musang Cave was used for habitation from approximately 10,000 B.C. to re cently. Two different assemblages were excavated. The earlier one consists of flake tools, shell, and animal bone, and dates from approximately 10,000-4500 B.C. Dur ing this time the cave was used as a frequentation site by hunters and gatherers. The second assemblage dates from approximately 4500 B.C. to recently. It contains the same type of flake tools, shell, and bone as in the earlier period, but also contains pottery, human bone, and a few beads, earrings and other ornaments, a brass needle, and other artifacts·. This assemblage is probably also the remains of hunters and gatherers, with the pottery and other new artifact types being obtained in trade from nearby agriculturalists. The site is important for several reasons. It is one of the earliest dated sites in Luzon. The pottery dates from 4000 B. c. or possibly earlier. This is some of the earliest dated pottery from anywhere in the Philippines. Also of importance is the brass needle. It is possibly as old as 2680 B. C., which is a very early date for brass.

In 1875, the desiccated remains of an Early Woodland boy were removed from Mummy Valley in Upper Salts Cave, Kentucky. Recent archaeological surveys in Salts Cave and forensic investigations of the mummy suggest that the boy was mortally wounded while mining cave minerals. Death resulted from an internal hemorrhage and apparently occurred in the cave. After death the boy was placed on the surface of a ledge in an area known as “Mumy” Hall.

The Trail Creek Caves are located in limestone cliffs on the west bank of Trail Creek, Seward Peninsula, Alaska. In 1928, the Deering Eskimos Taylor Moto and Alfred Karmun found arrowheads there. Test excavations were then carried out in Cave 2 in 1948. Unfortunately, the excavated material was lost in a fire at Nome. Between 1949 and 1950, the Dane Helge Larsen carried out further excavations in Caves 2 and 9. Various types of lithic artefacts were recovered. All excavated sections of the caves contained bones in an excellent state of preservation, some of which were very numerous. Ever since Helge Larsen published the investigation of the Trail Creek Caves 2 and 9, their early dates and the supposed presence of man there have been the subject of intensive discussion. This fresh study represents an archaeozoological analysis of the bone material from Caves 2 and 9 excavated by Larsen in the 1940s. It examines whether the bones were accumulated by man and which activities can be deduced from the archaeological remains.

Rose Cottage Cave is situated on the Platberg, just a few kilometres from Ladybrand in the eastern Free State (29i?½13'S; 27i?½28'E) (Fig.1). The cave is about 20 m long and 10 m wide. It is protected by a great boulder that encloses the front of the cave, leaving a sky light and narrow east and west entrances. The cave is being investigated as part of a research programme undertaken within the Department of Archaeology, University of the Witwatersrand. The current excavations, which began in 1987, follow two previous excavations, first, by B.D. Malan between 1943 and 1946, and, secondly by P.B. Beaumont in 1962.
