UPDATE 5:51 p.m.: A wildfire in Mariposa County continues to burn without any containment. The so called Detwiller Fire is located east of Lake McClure, northwest of the city of Mariposa.
The fire tripled in size overnight and reached 11,000 acres by Monday evening, and has forced some evacuations.
Scott McClean with CAL FIRE says heavy grass, brought on by a wet winter, is helping spread the flames.
"This is what's kind of acting like a fuse," McClean says, "very easy to ignite, and it's burning into the chaparral, it's burning into chamise, it's burning into a lot of brush fields that haven't burned in quite some time. I understand there's a lot of dead oak in that area as well."
The fire has destroyed one structure and damaged another. No cause has been determined.
There have been more than 3,200 wildfires in California this year. That's about 800 more than during the same period last year.

Officials have ordered an evacuation order for an unknown number of homes.
