The Castle Rock Fire Department was called to the scene in a suburb of Denver Friday evening. Rescue efforts were complicated by the horse's distance from the main road, forcing first responders to hike half a mile to the animal.

Firefighters spent two hours digging the horse out before they were able to secure the animal in a sling and drag it up a 10-foot embankment to safety. A veterinarian stayed on the scene until almost 4 a.m. treating and hydrating the horse.
It's not immediately clear how the horse became trapped in the mud.
