Photos and Shapefiles of Erosion/Deposition from the 20 July 2021 Black Hollow Debris Flow

This dataset includes photos taken in the field (Final_photos_for_data_release.zip) and a shapefile (Blackhollow_de.shp stored in Blackhollow_de.zip) to document debris flow activity in the Black Hollow watershed. The Black Hollow watershed was burned by the Cameron Peak Fire (13 August to 2 December 2020) and experienced a debris flow on 20 July 2021. The polygon shapefile in this dataset represents deposition and erosion from the debris flow. The deposition and erosion in the polygon were mapped by subtracting two lidar datasets (2021 and 2020) that were obtained from the USGS National Map (U.S. Geological Survey, 2024).
