Collection Overview: These data were acquired by the National Center for Airborne Laser Mapping (NCALM) on behalf of David E. Haddad (Arizona State University) as part of a Seed Grant awarded to him in 2009. David's MS research project, "Geologic and Geomorphic Characterization of Precariously Balanced Rocks" used these data and TLS datasets to understand the geologic and geomorphic settings in which precariously balanced rocks form in low-seismicity regions. He has kindly agreed to make these data available to the research community and the public through OpenTopography.Publications associated with this dataset can be found at NCALM's Data Tracking Center
