Plausible extents of landslide-dammed lakes in The Hole in the Ground, Owyhee River, OR
I have developed polygons showing likely extents of lakes related to both lobes of the Doublespring Landslide Complex on the Owyhee River. Using a combination of LiDAR data, ArcGIS, and GlobalMapper in conjunction with the highest plausible geomorphic evidence of fluvial overtopping the following lakes result:
East Spring Landslide: 878 m lake elevation.
West Spring Landslide: 868 m lake elevation.
The correspondence / lack of correspondence of these lakes with various upstream landforms and deposits is surprising.
