I think that might be what is causing the snow to do that. There need strict regulations regarding what aircraft are allowed to release at high altitudes. Chemicals like aluminum oxide, barium oxide, thorium oxide, strontium, silver iodide, sulfur dioxide, coal fly ash, and other chemicals should all be banned aboard aircraft. The only aircraft that should release anything other than engine exhaust are crop dusters used at low altitude to dust crops and firefighting aircraft releasing water to fight wildfires. Airports should be required to ground planes that have spray nozzles anywhere outside of the engines and have all chemtrail hardware removed in a maintenance hanger and those responsible for installing such hardware should be subject to fines, imprisonment, or both.
