Landslide Response: The Vermont Geological Survey is working with the Department of Forest, Parks and Recreation to assess the hazards associated with a large landslide in the Cotton Brook drainage in Waterbury, Vermont. VGS Geologists, along with researchers from Norwich University and University of Vermont, are mapping the extent and character of the landslide deposit. This will provide information on the size of the hazard, what trails are at risk, and the possible causes of the event. For more information visit the Cotton Brook Landslide page or a slide presentation from 7/9/2019

Landslide inventory for Vermont (in progress) is posted on the open data portal. There's an option to view the data on a webmap. The inventory will be updated annually as we inventory each county.
