Fire crews are reporting some progress in containing a smoky grassfire on the eastern side of Mt. Diablo.
As of Wednesday morning the fire was 80 percent contained and had burned about 375 acres along Curry Canyon Road near Clayton.
CalFire spokesman Daniel Berlant says there are structures in the area, but no homes have been evacuated and no major communities are threatened.
Winds are low, and the humidity went up overnight, so crews hope to contain the flames later Wednesday.
”We’re going to focus on the remaining 20 percent of the fire,” said Matt Streck with CalFire. “Most of it is in really steep rugged canyons where bulldozers can’t go, so we brought in some of our hand crews and they’re going to be physically cutting hand-line most of the day.”
One firefighter sustained a sprained ankle.
The cause of the fire is officially under investigation, but crews say it may have been caused by a downed power line found in the area.
