Human Activities and Environmental Changes during the Late Pleistocene to Middle Holocene in Southern Thailand and Southeast Asia

The Pleistocene—Holocene transition is bestknownin southern (peninsular) Thailand from two cave sites, one in the coastal lowlands and the other at a higher elevation in the interior. The first, Moh Khiew Cave, is situated in an isolated hill of Permian limestone in northern Krabi Province, southern Thailand (Figure 1). It is located about 10 m above mean sea level. In front of the cave, there is a small stream, Klong Krabi Noi, running north-south toward the sea, which is about 13 km from the site. The area surrounding the hill is covered with Quaternary sediments. The cave resembles a rock shelter, measuring 3 m wide by 30 m long, with its axis lying in an east-west direction.
