DENVER — Large wildfires grew across the American West on Wednesday, keeping thousands of people out of their homes for the July 4 holiday and forcing some strict bans on fireworks to prevent new fires from igniting in the hot, dry region.
The National Interagency Fire Center on Wednesday reported more than 60 large, active blazes across the country, most in the drought-stricken West where holiday festivities could lead to increased fire danger.
One of the largest recorded fires in Colorado history kept expanding, chewing through 147 square miles near Fort Garland, about 205 miles southwest of Denver.
The Spring Fire has destroyed more than 100 homes, and officials said preventing the flames from spreading toward the small mountain town of Cuchara is a priority.
Nearly 1,000 firefighters were working to gain control of the fire in unpredictable winds, but it was only slightly contained since sparking June 27.
Some fireworks displays were scheduled to go on in Denver and other large cities, but several mountain communities called off their holiday festivities to avoid any risk of flames.
In the southwestern mountain town of Silverton, a fireworks display was canceled in favor of live music and a parade. Aspen officials planned a fireproof display using drone lights in place of fireworks.
Parts of Colorado and other Western states have been grappling with severe drought that’s made wildfires explosive so far this season.
Utah authorities ordered more residents to evacuate as a blaze grew to about 62 square miles near a popular fishing reservoir amid high wind gusts, steep terrain, and dry conditions.
It wasn’t clear how many more people were told to flee, but several hundred homes and cabins have been evacuated and the orders were extended to a 20-mile area dotted with trees and cabins.
The fire roughly two hours southeast of Salt Lake City has destroyed about 30 structures. Officials in Utah closed a portion of Strawberry Reservoir so planes could scoop water and drop it onto the flames, but people could still boat and fish on other parts of the water Wednesday.
A nearby RV campground tucked among cliffs and canyons was closed, leaving those hoping to visit for July 4 to find another spot.
Darren Lewis and his extended family planned to spend the Fourth of July at a cabin built nearly 50 years ago by his father and uncle. Instead, Lewis and his family will spend the holiday nervously waiting to hear if a half-century of family memories go up in smoke.
‘‘There’s a lot of history and memories that go into this cabin,’’ said Lewis, 44, of Magna, Utah. ‘‘The cabin we could rebuild, but the trees that we love would be gone. We’re just hoping that the wind blows the other way.’’
