The condo building at 221 Mount Auburn Street in Cambridge, MA is being demolished due to structural issues. While I was walking by, I saw two snow guns in front of the building shown in the photo below. After asking around, I discovered that they were being used the wash dust associated with the demolition out of the air.
I know that hoses attached to the snowmaking hydrants have been used for supplementary water for forest fires. Anyone know of other applications of snow guns?
