We collaborated with the Army Corps of Engineers’ Cold Regions Research and Engineering Lab (CRREL) and the National Center for Airborne Laser Mapping (NCALM) in their development of CRREL’s “Helipod” lidar system, which made lidar data acquisition possible in the remote, high-relief, and densely vegetated terrain of western Glacier Bay National Park. Shad O’Neel and Dave Finnegan supported this collaboration; Darren Hauser and Ken Hudnut assisted with data processing. We thank Jim Kearns for boat transport in the field. The U.S. Geological Survey (USGS) Alaska Earthquake Hazards Project and Glaciers and Climate Project funded this research.
