A new Channel 4 series takes archaeology to the edge this summer as a team of experts tackles sites across the country that are beyond the reach of normal investigations. In Extreme Archaeology, an eight-part series starting on 20 June, a team of archaeologists with help from top climbers, cavers and divers investigates amazing and unique archaeological sites throughout the UK. Many archaeological locations are beyond the reach of your average archaeologist. They are found in inaccessible caves, on treacherous cliffs, deep under water, or in locations simply too remote or dangerous for normal investigation. Their remoteness often means that their secrets are unique, but they can also be under threat from erosion or other factors and this adds a rescue element to any investigation. Using some of the most advanced scientific equipment available, and high-tech miniature cameras and communication systems to record the action, Extreme Archaeology's experts are dropped into extreme and inaccessible environments under time and other pressures that test their personal and professional skills to the limit.
