This overview illustrates the uses of applied technology to provide enhanced levels of data control in restricted time frames, and for archaeological challenges to the viability of historic preservation in dangerous settings. Two examples of emergency rescue archaeology, one a Civil War complex under a contaminated Superfund site, the other a national monument damaged in natural disaster, illustrate the application of a range of applied technology solutions to the emergency rescue archaeology in extreme setting. Multiple categories of applied technology are discussed: all-weather field and laboratory operations, self-contained real-time data processing and information control, the use of GIS and geophysics in tandem with advanced 3D palaeo-environmental modeling to target areas of archaeological sensitivity in dangerous contexts. New classes of high speed non-contact 3D recording, single-camera computer-integrated photogrammetry and the first-generation of true-color 3D laser radar illustrate the ability of modern archaeology to do justice to our cultural resources to the highest standards without compromise. At the policy level, these strategies demonstrate the ability of modern archaeology to do justice to our dwindling culture history, even in highly dangerous, toxic, radioactive or ordnance-laced environments.
