Wildfires Force Evacuations At National Parks

3 days ago Visitors and staff at two national parks in the U.S. West have been evacuted because of wildfires. Officials at Black Canyon of the Gunnison National Park in Colorado say the park closed Thursday morning after lightning sparked blazes on both rims. Officials say conditions at the park have been ripe for wildfire with hot temperatures, low humidity, gusty winds and dry vegetation. The North Rim of the Grand Canyon in Arizona also closed Thursday because of a wildfire burning just outside the park boundaries. Fire officials say that blaze started Wednesday evening on Bureau of Land Management land.
