This airborne lidar dataset was collected by NCALM for Roman DiBiase at Pennsylvania State University. The data were collected immediately following the 2020 Bobcat Fire, prior to the first rainfall event, to quantify post-fire dry ravel accumulations in headwater valleys. The study area includes the region of Monrovia Canyon and Sawpit Wash in the San Gabriel Mountains, just north of Monrovia, California, and covers approximately 23 km2.
