Service Description: Lidar-derived elevation data for Wrangell Island, Southeast Alaska, collected November 28-29, 2023, Raw Data File 2024-1, provides an aerial lidar derived classified point cloud, digital surface model (DSM), digital terrain model (DTM), and intensity model of slopes above the Zimovia Highway on Wrangell Island, Southeast Alaska, during leaf-off conditions (cover figure). The survey provides snow-free surface elevations for use in landslide hazard assessment following a November 20, 2023, debris flow that occurred near Milepost 11 of the Zimovia Highway and tragically claimed the lives of six people. Ground control data were collected June 26-30, 2023 (Zechmann and others, 2023), and aerial lidar data were collected November 28-29, 2023, and subsequently merged and processed using a suite of geospatial processing software. This data collection is released as a Raw Data File with an open end-user license. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/31106).
