3.  Increased dust may aggravate respiratory ailments (indoor and outdoor air quality concerns)  Decreased visibility  Damage to infrastructure  Deposition of dust on snowpack – decreases snow albedo, speeds snowpack melt  positive feedback loop

7.  EEOP is cosponsoring dune stabilization projects along with the US Geological Survey  Techniques  Mud balls  Native plant seeds  “Sand sausages”  Wind erosion buffer
