document: Firefighters in California , Michigan , Montana , Wyoming and Utah battled holiday weekend fires which blackened more than 6,000 acres of forest and wilderness areas . Illegal fireworks were blamed for a blaze that swept over 2,200 rugged acres of Stanislaus National Forest in California , 10 miles west of Yosemite National Park . The fire , which began Saturday , was declared contained this morning , `` We have evidence confirming that it was a bottle rocket , '' said Mary Hale , a spokeswoman for the California Department of Forestry . The fire was the largest in the forest this year . Stanislaus was the scene of huge wildfires last summer . In southern Utah 's scenic Zion National Park , firefighters tried today to contain a 600-acre fire that was ignited by lightning June 19 but had been allowed to burn in a small area . However , on Sunday , winds ranging from 30 mph to 60 mph fanned the flames out of control , Chief Ranger Bob Andrew said . Firefighters , assisted by water-carrying aircraft , expected to have the blaze contained by midday . No injuries or property damage were reported . A four-day fire in 1,100 acres of Hiawatha National Park in the Upper Peninsula of Michigan was also said to be under control , although continued hot dry weather could mean weeks before the fire is extinguished . `` It 's been real quiet out there , '' Sgt. Terry Leisening of the Delta County Sheriff 's Department said today . `` I think they 've got it just about out . '' U.S. Forest Service spokesman Dale Bluedorn agreed , but said they will continue to keep patrolling . `` It may not be declared out until there 's a three-day rain , '' he said Monday . A small contingent of firefighters who hiked into the Absaroka-Beartooth Wilderness on Monday in south-central Montana contained portions of a 2,000-acre fire that has been burning there since June 19 , forest officials said . Forest Service policy allows wilderness fires to burn unless they threaten trails or structures , or threaten to burn outside the wilderness boundary . The firefighters were called in to stop the flames as they neared the Stillwater River Trail inside the wilderness area . High winds Saturday tripled the fire 's size . Phil Jaquith , Beartooth District ranger for the Custer National Forest , said the bulk of the fire on the east banks of the Stillwater River was not being suppressed . Cooler temperatures and calmer wind played a role in getting the blaze contained on the west riverbank , which is about two miles from the trail , Jaquith said . Three-quarters of an inch of rain on Monday helped slow a fire on 1,650 acres in the Shoshone National Forest in Wyoming , and rain also damped fires in Yellowstone National Park . Fire information officer Dave Damron said water was also being pumped out of bogs in the Shoshone forest to help contain the fire . Firefighters concentrated on keeping the fire entering the Du Noir Special Management Area a few miles to the north , Damron said . Meanwhile , a fire which burned 8,700 acres in the Tonto National Forest north of Phoenix , Ariz. , was reported extinguished on Monday .
