DENVER (KDVR) — A man was rescued from near Guanella Pass with frozen shoes after his father called 911 to alert authorities of the overdue hiker. According to the Alpine Rescue Team, the volunteer group was called to Mount Bierstadt on Friday after 8 p.m. The man had set out in the morning to climb the peak, setting off from the winter trailhead, and told his father to call 911 if he didn't hear anything from the hiker by 8 p.m. Alpine Rescue Team members began their search at the top of Guanella Pass on the summer trail. At about midnight, a team near the creek crossing saw a light flashing a mile north of their location. The team broke trail in that direction. At about 1 a.m., the volunteer team found the man above a small cliff band. The crew said he was "unable to move as his shoes had frozen solid." After climbing a short distance, crews were able to reach the man and warm his feet, followed by a short belay to the ground. Teams then hiked/skied with the man and exited the field after 3 a.m. on Saturday. The group said that the man asking his father to call 911 after a certain cutoff time may have saved his life, as his father may have called 911 far later. The team also advocated for hikers to pack extra layers of clothing in case of getting the clothes they're wearing wet, and said to bring a light source. Aurora firefighters say propane grill caused house fire that displaced 2 families of 5 "(H)ad our subject not had a light source, it's unlikely he would have been able to signal the team," the group said on Facebook.
