Grossman 2007 Note: True-color laser-radar scan of flood-damaged remains of the 1830 Furnace Falls Dam of the Morris Canal National Historic District. The new and just released millimeter-precise (4 - 6 mm resolution), true-color, terrestrial 3D laser-radar (Lidar) technology for the first time permits the archaeologist to document important archaeological resources in dangerous settings to the highest Department of Interior and HABS/HAER standards, from the safety of virtual space, after the emergency field operations are completed (Grossman 2004, Figure 50; See Grossman, 2007b, Archaeology of Toxic and Hazardous Environments, Encyclopedia of Archaeology, Pearsall (D), Ed., Elsevier / Academic Press, Oxford, England).
