Collection Overview: This 2018 airborne lidar dataset was collected by NCALM for the NSF-funded project, "Topographic response to the transition from snowmelt- to rainfall- triggered extremes". This study uses lidar data to characterize hillslope and river network properties to understand how rainstorm and snowmelt runoff drive large floods, erosion, and the long-term evolution of landscapes. The survey area is located northwest of Colorado Springs, CO and covers approximately 557 km2.Publications associated with this dataset can be found at NCALM's Data Tracking Center
