    Collection Overview: NCALM logo This lidar dataset was collected as part of an NCALM Seed grant for Kirk Townsend at the University of Michigan. This study examines the role of extreme events in setting the pace and magnitude of landscape change with post-fire debris flows in the Santa Monica Mountains of Southern California. The study area covers approximately 60 km 2 near Zuma Creek, California.
