First Tuesday: Beauty and the Beast - Lidar Imagery and Debris Flows

When: Tuesday, November 3, at 7pm. Where: The Winthrop Barn (Get Directions) Join the Methow Conservancy, the Methow Watershed Council, and the Washington Geological Survey for a First Tuesday talk all about flooding, debris flows, and the stunning lidar imagery that can help us understand these phenomena on our home landscape. Beauty and the Beast: How lidar reveals stunning landforms and geologic hazards with Daniel Coe and Emilie Richard, Washington Geological Survey In the past few decades, the increasing prevalence of lidar (laser-derived terrain data) has allowed geoscientists to "see through the trees" and accurately map landslides, faults, glaciers, and other geologic features with much greater detail and accuracy than with previous technologies. This talk will share examples of lidar-based landform images from across the region and highlight the usefulness of lidar-based alluvial fan mapping in the Methow Valley. Daniel and Emilie will explain how flooding and debris flows form alluvial fans and how wildfire increases these hazards, drawing on recent mapping and ongoing research, including some research from right here in the Methow Valley. ----------------- This presentation is free and open to the public.
