Devil's Lair is an archaeological cave site located in Western Australia, which earliest has been dated to approximately 41,000-46,000 years ago and perhaps earlier still. The site is a large limestone cave consisting of four nested hearths, the lowest of which has been dated using OSL to between 41,200-46,500 years ago, consistent with radiocarbon dates on younger layers.
Very few artifacts have been recovered from these layers, and some of them may have been washed into the cave by erosion. The site was excavated by Charles Dortch in the 1970s.
