Wildfires threatening US national park landmarks

Wind has wreaked havoc with wildfires threatening two crown jewels of the US National Park Service, pushing the flames towards man-made and natural attractions in and around Glacier and Yosemite national parks.

The wind-driven fires, combined with high temperatures and dry conditions, have disrupted holiday travel and hampered firefighters across the West during a Labour Day weekend that capped a devastating summer in which an area larger than Rhode Island has burned.
