Map: Park Fire’s active burning prompts more evacuations

New evacuations were ordered in Tehama County, and the following day the fire crossed Highway 172.

Two weeks after it started, the Park Fire is burning actively toward Mount Lassen, and firefighters are bracing for more high temperatures and low humidity.

As of the first report on Wednesday, Aug. 7, from the California Department of Forestry and Fire Protection, the fire had burned 420,827 acres (657 square miles) — an increase of about 7,000 acres in 24 hours. Containment was 34%.

The growth was an arm extending along Mill Creek in Lassen National Forest. On Monday night, new evacuations were ordered in that area of Tehama County. The following day, the fire crossed Highway 172 near Jones Valley, CalFire said.

It was about 7 miles south of Lassen Volcanic National Park, which has been closed since July 27 because of the fire.

The map above shows the approximate perimeter of the fire as a black line, and the evacuation zone in red.

As of Aug. 7, 600 square miles was under evacuation order. Except for three Butte County zones along Highway 32, all of the orders were in Tehama County.

The fire started July 24 in a park at the edge of Chico. Arson is suspected.
