Meanwhile near Taggart, in Morgan County, the 200-acre Tunnel Hollow fire threatened to shut down Interstate 84 as of 8:45 p.m., said fire spokesman Jason Curry.
A third fire, also in Tooele County, closed Lookout Pass on the Pony Express Trail near Vernon. The Sheep Fire had reached 1,780 acres late Monday.
Lightning bolts from a series of weekend thunderstorms sparked more than 20 northern Utah wildfires; crews had snuffed most of them and were well on the way to containing others by Monday.
Not started by lightning, but from so far unspecified human action, was the Indian Fire just east of Ogden. That blaze, first reported Friday evening, was 95 percent contained Monday night after burning about 50 acres of grass, oak brush and timber.
Approaching flames initially forced evacuation of 20 homes from 1850 South to 22nd Street, but none of the structures were lost and residents had all returned as of Monday morning.
The specific cause of the fire remained under investigation.
Meanwhile, the Flats Fire, burning near Indian Peak in Beaver County, remained uncontained after scorching 160 acres since it began on Sunday. Its cause remained undetermined.
The North Summit Fire District remained busy responding to lightning strikes, and crews were successful in limiting most of the resulting blazes to less than an acre. However, one wildfire, just east of Henefer, had burned 120 acres before crews hemmed it in early Monday morning.
The cause of that fire also was under investigation, as was a Sunday night blaze that heavily damaged the Ross Brothers Feed and Seed plant in the Duchesne County town of Myton.
That fire was out by 8 p.m., and a brief evacuation of nearby homes was lifted, dispatchers said.
