One middle Pleistocene : Spencer and Jaffee 2002 Thesis Paper— Medley Flood Sites
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.
These flood deposits contain clues about the number, timing, and magnitude of individual flood events. Modern analysis of rhythmite sequences and clast composition continues to refine our understanding of the flood chronology.
These sites document Missoula Flood deposits identified by researchers studying the downstream effects of the catastrophic flooding through the Columbia Basin, Columbia Gorge, and into the Willamette Valley.
