(CBS4) – On Thursday morning officials at Colorado’s most popular national park took the extreme measure of closing the entire park to visitors due to the dangers posed by a devastating wildfire. Rocky Mountain National Park is closed due to the extreme fire behavior of the East Troublesome Fire, which is now listed at more than 125,000 acres. On Thursday afternoon officials said the fire has jumped across the Continental Divide.

The fire burned 100,000 acres on Wednesday and crept past the park’s western edge.
