The AdAmAn Club departed Monday morning up the Barr Trail for their annual fireworks show on the summit of Pike Peak.
Weather conditions are forecast to be clear Tuesday night, but with brutal cold and wind at the mountain summit.
Temperatures will fall within a degree or two above zero after 4pm Tuesday, with the winds blowing between 15 to 30 mph and gusting to 50 mph by midnight.
This will drop wind chill values down to -25 degrees below zero after 6 pm.
