This is one of more than 1,800 field sites cataloged in the early scabland surveys — the bedrock of the Ice Age Floods scientific record. The Bretz-era researchers walked the ground first; modern cosmogenic dating, LiDAR, and remote sensing have since extended and refined what they mapped.
Every site along the trail will receive the full Terrain360 capture treatment: ground-level 360° panoramas, drone aerial imagery, and photogrammetry-based 3D models that visitors can spin in their browser. This page reserves the slots; the imagery flows in as field capture completes.
Ground-level 360° panorama, every step along the feature, captured by Terrain360 field crews.
Drone flyovers reveal the geometry of catastrophe — ripple marks, gravel bars, and scour patterns invisible from the ground.
Photogrammetry and Gaussian-splat models let visitors rotate, measure, and inspect features in detail-page WebGL viewers.
Mapping ice sheet margins is critical for understanding the timing and extent of glacial lake formation. Modern cosmogenic dating and LiDAR surveys continue to refine the ice sheet chronology in the Pacific Northwest.
Researchers studying Pacific Northwest ice sheet margins mapped the extent of the Cordilleran Ice Sheet, whose advance and retreat controlled the damming of Glacial Lake Missoula and the release of the catastrophic floods.
