Officials have set a goal date for containment of the nearly 4,000-acre and, so far, 0% contained South Rim Fire that has been burning in Black Canyon of the Gunnison National Park for days.

Rapid growth on the South Rim fire in Black Canyon of the Gunnison National Park forced immediate evacuations in Montrose County on Saturday afternoon.

The South Rim Fire has burned more than 3,600 acres uncontained since sparking Thursday along the canyon's rim as of Sunday night, and officials Sunday said the fire had started spreading into the canyon itself.
