Unconsolidated > Coarse-detrital > Sand (Eolian)Large areas of windblown sand composed of rock-forming minerals, mostly feldspar and small amounts of quartz, and, in southeastern Oregon, also pumice
|Comments||Eolian deposits not included in State map in La Grande area, but mapped in OR291, where it contains 0.5-1-m-thick accumulations of Mazama Aas (6.7 ka). Eolian deposits also mapped in the Hermiston area, northwestern Umatilla River Basin (OR292) near Columbia River|
