Fire crews in and around Yellowstone and Grand Teton national parks mobilized Thursday to contain a series of small fires sparked by lightning from mid-week thunderstorms, as well as one blaze that may have started from a campfire.
Though the fires are small and have not required road or campground closures, fire managers in the parks and on other nearby public lands are aggressively working to extinguish some fires that could potentially threaten buildings or other key resources. A dry, hot summer and high winds have created prime fire conditions across much of the region.
