In 1972, a protracted cold spell held an icy grip on metro Denver, when maximum temperatures never reached above freezing for 10 consecutive days from the 3rd through the 12th and minimum temperatures dipped below zero on eleven consecutive days from the 5th through the 15th. The very cold temperatures were caused by 3 to 5 inches of snow cover and a Canadian air mass. $$
