OGDEN -- Firefighters are working to extinguish a fast-moving fire near the mouth of Ogden Canyon.
About 40 to 50 homes on the east side of Maxfield Street and along 1300 South have been evacuated as a precaution.
No structures have been damaged, although fences at several homes were damaged by the flames.
The fire was first reported about 6:30 a.m., according to Ogden Deputy Fire Chief Matthew Schwank.
About 10 to 12 acres had burned as of 8 a.m., but firefighters believed they had the blaze under control.
Winds in the canyon reached about 20 miles per hour and caused some issues in fighting the fire.
Schwenk said it will probably be 9 a.m. or later before residents are allowed back in their homes.
Tom Chambers, who lives on Victory Road, said he has "everything ready" to leave his house in case of fire because "the hill is drier than hell." He was not among those who were evacuated.
The fire is believed to have started near restrooms west of the Bonneville Shoreline trailhead, about 100 yards west of the mouth of Ogden Canyon.
Schwenk said the cause of the fire is not yet known and the state fire marshal is en route to help determine how the blaze started.
