Firefighters Make Progress on California's Massive Park Fire

Containment reaches 30% as cooler weather aids efforts, but rising temperatures pose new challenges.

The Park Fire has burned over 401,000 acres, becoming the fourth-largest wildfire in California's history.
Fire crews have contained 30% of the blaze, benefiting from recent cooler weather and increased humidity.
Triple-digit temperatures and dry conditions forecasted for the coming days could increase fire activity.
The fire, caused by arson, has destroyed 572 structures and led to evacuations in Butte and Tehama counties.
Challenging terrain hampers firefighting efforts, with inaccessible areas preventing the use of heavy machinery.
