Tourists and residents around Montana’s Glacier National Park were fleeing a wildfire that is shutting down tourism in the area.

Officials say that most of the part’s major attractions are still open but that flames drove away campers because of the smoke rising over the ridge tops.  Over six square miles of the park have burned during what is considered the height of the tourist season.

Over 600 campers fled the St. Mary Glacier Park KOA Campground and were replaced by fire officials that have turned the camp into a makeshift staging area for fighting the fire.

The cause of the fire is still under investigation.

Meanwhile, a wildfire in California shot flames more than 100 feet into the air and is threatening 200 homes and ranches in the Napa Valley area

The flames had spread to 10 1/2 square miles and the smoke from the fire could be seen in Sacramento and San Francisco.
