Mostly on terraces and pediments above present flood plains. Includes older alluvium of Smith and others (1982) in the Klamath Mountains and both high- and low-level terraces along Oregon coast. Includes dissected alluvial fan deposits northeast of Lebanon, and Linn and Leffler Gravels of Allison and Felts (1956)","comments":"In OR291, includes terrace levels 60 m and 20-30 m above Grande Ronde Valley floor.  Lower terrace dated as Pleistocene based on radiocarbon date of a mammoth tooth of 15,280+180 yr B.P.  In OR292, includes a terrace that stands 20 m above the modern valley floor along the south side of the Umatilla River.
