Map of erratics

While researching for erratics, I found a nice map showing the location of all the erratics in Willamette Valley.

Maps Showing Inundation Depths, Ice-Rafted Erratics, and Sedimentary Facies of Late Pleistocene Missoula Floods in the Willamette Valley, Oregon

I think the map also shows that the erosional patterns is not consistent with a flood from an ice dam, but is more consistent with my Wallula Gap dam hypothesis.
