The report describes the procedures for and the results of field tests conducted to stabilize snow by chemical treatment. Sintering of the snow by spraying methanol on its surface suppresses a possible white out condition when helicopters perform normal take-off and landings upon the treated areas. The addition of a violet dye to the methanol also provided the aircraft pilot with a definitive form of reference when the ground was covered with snow and no nearby markers were present.
