Park County officials issued the mandatory evacuation order Sunday afternoon for the Ranch of the Rockies subdivision, which is about 75 miles west of Colorado Springs on the Park County border. It was not immediately known how many people lived in the evacuation zone. The fire was reported around 11:30 a.m. and initially covered five acres.
