Grand Canyon's North Rim closed due to Arizona wildfire as separate blaze near Tucson grows

A portion of Grand Canyon National Park remains closed as a wildfire in Northern Arizona still burns through a national forest, as forecasters warn the weather this week will create more dangerous conditions.

The North Rim of the Grand Canyon has been closed since Friday after the blaze dubbed the Mangum Fire has consumed some 20,000 acres.

Officials said the fire is burning within the Kaibab National Forest, moving northeast, and not within the national park.
