PI: Sam Johnstone, Stanford University. The requested survey area is an irregular polygon located 10 km east of King City, California in the Wildhorse Valley of the Gabilan Mesa. The data were collected to investigate the impacts of valley alluviation on hillslope-channel coupling. The polygon at its widest point is approximately 13 km long by 5 km high and encloses approximately 75 square km. The survey took place on August 11, 2013.Publications associated with this dataset can be found at NCALM's Data Tracking Center Dataset Acknowledgement: Lidar data acquisition and processing completed by the National Center for Airborne Laser Mapping (NCALM - https://ncalm.cive.uh.edu).
