The Fraiser Creek Fire was just one of several small wildfires across Idaho on Monday morning that were keeping crews from federal firefighting agencies as well as rural fire departments busy amid temperatures in the 90s and dry, gusty conditions.
About crew of about 150 were fighting the Fraiser Creek Fire about 150 about five miles east of Banks as it consumed grass and timber.
The Fraiser Creek subdivision, a 40-structure neighborhood not far from the Payette River, is within about a half mile of the fire, though crews including those from rural fire departments in nearby communities of Garden Valley and Horseshoe Bend are building a fire line after knocking down flames on that side of the blaze.
"The cause of the blaze is under investigation, but likely person caused," said U.S. Forest Service spokesman David Olson, in a statement.
There is no estimate of containment but State Highway 17 was open for traffic.
Travelers need to use caution due to the potential of rock fall onto the road, Olson said.
South of Declo in Cassia County, the Guinn Fire was estimated at just under a square mile, but was expected to be contained on Monday as a crew used five fire engines, a pair of bulldozers, a helicopter and one tanker to trim its advance across grass and sagebrush.
And fire officials with the Boise District of the Bureau of Land Management said two fires that were likely touched off by lightning were due to be contained by Monday afternoon.
One was the Hidden Hollow Fire near Emmett, which had consumed a small patch of rocky terrain north of Emmett, and the other was the Strike Fire near the C.J. Strike Reservoir on the Snake River southeast of Boise, where four engines, a bulldozer and a water tender were working to contain the blaze at just 39 acres.
