What happened

The episode as NWS CYS wrote it up.

Winter storm conditions caused by fresh snow and strong winds contributed to 76 accidents from 2200 12/08 to 1700 12/10 in Laramie and Albany counties. 17 of the accidents involved injuries, the exact number of which are not known. 21 passengers on a bus were injured 12/10 when the bus rear-ended an eastbound semi-truck approximately 14 miles west of Cheyenne. The accident was attributed to icy roads and blowing snow. On 12/11, a 73-year-old woman died while trying to reach her ranch on foot after her vehicle became disabled. Her body was located in an abandoned mobile home approximately one-half mile from her vehicle, near the Horse Creek Ranch along the county line between Laramie and Albany counties. The temperature at the time was approximately 20 degrees below zero with wind chills in the vicinity of 70 degrees below zero.
